most impossible

[rapid tendon]

here

it says its a point on the line

so thats how u find points on a line okay?

this one is a quadratic

[jagged mesa]

ok

yea

[rapid tendon]

so we can go over quadratics

[jagged mesa]

alrr

[rapid tendon]

alright

$y=ax^2 + bx + c$

[naive grotto]

Jam

[rapid tendon]

how do we find the roots of this equation?

its what your teacher said now

to find the roots you set something to 0, what is it

https://www.desmos.com/calculator
heres the app i use to draw lines and curves etc

[jagged mesa]

ok

first though

what are roots

[rapid tendon]

how do we find the roots of this?

[jagged mesa]

like the start?

[rapid tendon]

roots are

where the line cuts the x axis

[jagged mesa]

ok

but i need numbers right

y = 0 anyways

[rapid tendon]

ye

perf

so

do you know how to solve quadratics first

like this one

$x^2 -2x -3 = 0$

[naive grotto]

Jam

[jagged mesa]

nope

i forgot

[rapid tendon]

alright

so first thing we do

is find the factors of -3, the y intercept
then find the pair that multiply to make -2

what are the factors of -3

[jagged mesa]

ok

factor

uh

[rapid tendon]

what numbers multiply to make -3

[jagged mesa]

o alr ye

-3 and 1

wait

can u even do that lo

[rapid tendon]

theres one more

no thats right

-3 and 1 is a factor pair of -3

[jagged mesa]

no repeats?

like

[rapid tendon]

whats the other pair

[rapid tendon]

u can repeat the numbers and change the signs yes

[jagged mesa]

-1 and 3

[rapid tendon]

perfect

those are your two pairs

-3 and 1
-1 and 3

[jagged mesa]

yes

[rapid tendon]

which of these

when you add them

give you -2

[rapid tendon]

because of the -2x here

we need the pair that add for -2

[jagged mesa]

-3+1

[rapid tendon]

1-3 = -2

perfect

so the pair -3 and 1 is the pair you use

$x^2 -2x -3 = 0$

[naive grotto]

Jam

[rapid tendon]

split the -2x into -3 and 1

$x^2 -3x+x -3 = 0$

[naive grotto]

Jam

[rapid tendon]

do you know how to factor from this?

if you are busy, i can go through this another time

[jagged mesa]

weres 1

[jagged mesa]

no

[rapid tendon]

the 1x

[jagged mesa]

alr

[rapid tendon]

=3x + x = -2x

]

this is equal to

[jagged mesa]

but i dont think this will be on it

[rapid tendon]

this

[jagged mesa]

its just

[rapid tendon]

this is a quadratic

[jagged mesa]

theres a way to put this into calculator

[rapid tendon]

exponential

[jagged mesa]

my teacher said this was exponential

i did it in class

[rapid tendon]

this is the exponential

[rapid tendon]

this is the quadratic

[jagged mesa]

one sec

[rapid tendon]

aight

[jagged mesa]

lemme get my maths stuf frq

ok lemme see

so on the graph i have

its like

-36

then it goes to -15

then 0

[rapid tendon]

can you send a picture?

[jagged mesa]

then (1,10)

sadly i cant

but

[hybrid saffron]

mb

[jagged mesa]

look ill explain how it was got

[rapid tendon]

hey dark

[jagged mesa]

hi dark

[hybrid saffron]

so are we doing exponential or quadratics first?

[rapid tendon]

do you have the equation

of the line

[rapid tendon]

first q is quadratic

[jagged mesa]

but the solution wasnt quadratic

it was exponential

cuz u put smth into the calculator

[rapid tendon]

the solution will be a constant

[hybrid saffron]

wdym "the solution"

be specific

[rapid tendon]

the roots

[jagged mesa]

solved

[hybrid saffron]

a solution cannot be an exponential

[rapid tendon]

also the answer to that isnt an exponential graph

[jagged mesa]

thats not what i meant

[rapid tendon]

its literally asking u to draw a quadratic

so it will be a quadratic

[jagged mesa]

i meant it being solved

[rapid tendon]

for x?

[hybrid saffron]

are you asking about $10x-4x^2=0$?

[naive grotto]

dark matter

[jagged mesa]

yes

no

not = 0

[hybrid saffron]

what.

[rapid tendon]

how do you solve

if its not =0

or =anything for that matter

[jagged mesa]

u put it into a calculator

i just dont have one me to explain

wait

[rapid tendon]

$\frac {10}4 * x -x^2 = 0$

[naive grotto]

Jam

[rapid tendon]

$ x(\frac {10}4 -x)= 0$

so one solution is x=0

[jagged mesa]

ok so

[rapid tendon]

x= 10/4

[jagged mesa]

u press menu

[rapid tendon]

is the other solution

[jagged mesa]

then go to table

[rapid tendon]

10/4 and 0

[jagged mesa]

then on the calculator it says

f(x)=

then u put in

10x-4x^2

[rapid tendon]

casio ?

[jagged mesa]

and when u put that in

it says

[rapid tendon]

u get a table ye

[jagged mesa]

g(x)=

[rapid tendon]

im assuming u have a casio cuz mine does that too

[jagged mesa]

and for this its apparently -2

[rapid tendon]

my calc

[jagged mesa]

yes its casio

[rapid tendon]

for this just dont do g(x) lol

lemme g et my calc

[jagged mesa]

u need to for the way we are told to do it

but wth is g(x)

and hows it -2

like it says at th top

-2<x<2 for x E R

which idk

[rapid tendon]

listen

what yo udo is

f(x)=

then you put in this

then for g(x) skip it by pressing =

then for the part where it says

start, end, step

start is -2

end is 2

step is 1

then just draw accordingly to the points it gives you

[jagged mesa]

o

ok*

[jagged mesa]

OHH

[rapid tendon]

try it

[jagged mesa]

THAT MEANS START END STEP??

[rapid tendon]

wdym

[jagged mesa]

i didnt know what it meant

[rapid tendon]

the g(x) is just another function ignore that

start end step is

[jagged mesa]

that is start

[rapid tendon]

start is where the graph starts

nah

[jagged mesa]

thats were i was told to put start

[rapid tendon]

oh

well

hey

idk how ur calc works

what model calc do u have

i have

[jagged mesa]

were does it say model

[rapid tendon]

cassio fx=991ex classwiz

top left

for mine

[jagged mesa]

fx-83gt classwiz

[rapid tendon]

i see

[jagged mesa]

so

the first like

for example

ima say randoms

-4 < x < 4

-4 would be the start?

[rapid tendon]

start is -4

end is 4

[jagged mesa]

OHHH

THAT MAKES SO MUCH SENSE

what do we do with the end tho

[rapid tendon]

step is how many it goes in

do u have a phone on u

can u send a picture of each screen

after i tell u what to press?

[hybrid saffron]

do you understand what $x\in\bR$ means?

[naive grotto]

dark matter

[jagged mesa]

no

[rapid tendon]

is this what u have

[jagged mesa]

mines broke lolol

[jagged mesa]

no mines blue

[rapid tendon]

does it look like that

tho

[jagged mesa]

this

[rapid tendon]

thx

il find it

[hybrid saffron]

okay, it basically says that x has to be in the real numbers

[jagged mesa]

ohhh

[jagged mesa]

ok

[rapid tendon]

does it show you this

[hybrid saffron]

then, $x\in\bQ$ means for x in the rational numbers

[naive grotto]

dark matter

[hybrid saffron]

$x\in\bN$ means for the natural numbers

[rapid tendon]

where you can input values in for this line

[naive grotto]

dark matter

[rapid tendon]

like you can put numbers in this

[jagged mesa]

it doesnt show that

[hybrid saffron]

and the most common, $x\in\bZ$ is for the integers

[jagged mesa]

it shows after u put in

[rapid tendon]

wowzers

[naive grotto]

dark matter

[jagged mesa]

everything

[rapid tendon]

does it ask step end start

[jagged mesa]

like put in the functions n stuff first

[jagged mesa]

it only asks for g(x) =

which is start]

apparentl

[rapid tendon]

im gonna be honest g(x) is another function

its like putting 2 lines

[jagged mesa]

wait no

it does short

start end step

but

[rapid tendon]

yes

[hybrid saffron]

$x\in\bR$,$x\in\bQ$, $x\in\bN$, $x\in\bZ$, and $x\in\bC$ are all symbols you will see

[rapid tendon]

you put the start end step there

[jagged mesa]

not on mine

[rapid tendon]

g(x) is another func just pres = there theres no need to do anythin there

hmm

well idk i dont think using that calc is the most reliable for graphs then

id just draw a table and input values

[jagged mesa]

everyone in my class uses it

[rapid tendon]

theres something weird goin on

@hybrid saffron

f(x) and g(x) are functions right

[naive grotto]

dark matter

[hybrid saffron]

yes, why are you asking?

[rapid tendon]

hes sayin g(x ) is where u put the bounds

in a calculator

like

-2<x<2

apparently on that calc u put bounds in g(x)

[hybrid saffron]

i have never, in my life, used a piecewise function on a calculator

[rapid tendon]

that cant be right

[jagged mesa]

well my teacher said to put -2 in there

[rapid tendon]

well ya but

g(x)

is a function for graph

not a bound input

[rapid tendon]

well i hope it works then

do u have the calc on u

[jagged mesa]

YE

ye*

[rapid tendon]

bet

put in

10x^2-2x

and give me values from 3-5

x=3, 4, 5

[hybrid saffron]

did i get ghost ponged

[jagged mesa]

wym values

[rapid tendon]

i dont think so

[rapid tendon]

y values

as this is how the graph function on your calculator is intended to work

[jagged mesa]

so 10x squared - 2x

?

[rapid tendon]

yes

[jagged mesa]

what do i put for g

[rapid tendon]

hey its your calc

no irea

idea

press = there

see what happens

[jagged mesa]

ok

[rapid tendon]

after u press = on g(x)

what happens

[jagged mesa]

and table range?

[rapid tendon]

there u fo

table range

is exactly what i mean

[jagged mesa]

start 1:

end :5

[rapid tendon]

by step start and end

[jagged mesa]

step :1

[rapid tendon]

put start as 3

[jagged mesa]

how do i put

it dont let me change

[rapid tendon]

just press a number after its flashing on it, then press =

or like bold

press a number then = to do it

it should say

start 3
step 1
end 5

[hybrid saffron]

do you have a window changer, by chance?

[rapid tendon]

whats that

[jagged mesa]

oh it worked

[rapid tendon]

there

thats how you are supposed to use the graph function

[jagged mesa]

so start 3

end 5

[rapid tendon]

not whatever your teacher is saying

[jagged mesa]

step 1?

[hybrid saffron]

where you can set the bounds of a function, but i suppose it only works for a ti84

[rapid tendon]

once it looks like this press = and there u have ur values

[jagged mesa]

ok

[jagged mesa]

my f(x) is diff to urs

[rapid tendon]

thats table range mayb

[rapid tendon]

whats it say

[jagged mesa]

84 152 and 240

[rapid tendon]

oh thats cuz

i used a different grapg

graph

lemme use the right one

what was fx

10x^2 -2x rifht

[jagged mesa]

10x^2 - 2x

ye

[rapid tendon]

see

thats how you use the graph function

not some g(x) bs

[jagged mesa]

alr lol

so

if we do it for the one

[rapid tendon]

back to this

ye

put the function in

then put start -2

end 2

step 1

[jagged mesa]

ohhh

ohh

i see

yes

ok

[rapid tendon]

scroll down for the rest of the values

and then draw dots and join em up

[jagged mesa]

i got the same thing as i would

with the g x

so atleast they are both right

but ill def use this instead

[jagged mesa]

and it makes alot more sense

[rapid tendon]

if u put gx = -2

it will just output -2 forever

[jagged mesa]

oh

[rapid tendon]

start and end are the bounds

a<x<b

[jagged mesa]

why the hell did my teacher say all that then 😭

[rapid tendon]

a= start

b= end

[jagged mesa]

HE COULD OF GOT ME COOK IN TEST

[rapid tendon]

you said he said quadratic is an exponential, i dont have high expectations lol

[jagged mesa]

could u graph it for me then?

i waan see what the graph looks like

[rapid tendon]

quadratic

exponential

[rapid tendon]

the 10x-4x^2?

sure

[jagged mesa]

mhmm

[rapid tendon]

negative x^2 term so it will look like a n

and y intercept is 0 as there is no c

[jagged mesa]

see my graph looks like

[jagged mesa]

so imagine this

[jagged mesa]

i prolly got the numbers a bit off but

[rapid tendon]

these are just some of your points

all of them exist on this line

[jagged mesa]

(-2,-36)

[rapid tendon]

see

-2,-36

[jagged mesa]

(-1,14 or -1,15)

then just (0,0)

[jagged mesa]

and then its like

[rapid tendon]

i wont send the rest of the points since you get the idea

it all exists on this line

[jagged mesa]

i cant rlly see the last one

ye

[rapid tendon]

wdym

the 0,0?

[jagged mesa]

so thats wrong what the teacher did

no no

[jagged mesa]

i meant on my paper

[rapid tendon]

o

[rapid tendon]

idk what your teacher taught but this is the correct way to use a calculator

[jagged mesa]

alr

do i try the next then

by my self

[rapid tendon]

yes

same bounds

-2<x<2

[jagged mesa]

mhm

[rapid tendon]

f(x) = 3^x

[jagged mesa]

the tabl looks weird

[hybrid saffron]

it is scaled

[jagged mesa]

scaled?

SO ITS LIKE

i mean

[hybrid saffron]

not precise dimensions

[jagged mesa]

so on the calculator

[hybrid saffron]

on calcs, its usually not scaled

[jagged mesa]

f(x) 0.1111

0.3333

1

and then 3

how tf would i plot that

[hybrid saffron]

for what?

[rapid tendon]

on the question paper, the y and x axis dont have equal numbers

so they arent squares, rather rectangles

[rapid tendon]

0.333333… is 1/3 right?

a point on 1/3

[jagged mesa]

oh

wym 1/3?

[rapid tendon]

just write the x,y coords draw on graph

[rapid tendon]

0.33333… is 1/3

as a fractuon

[jagged mesa]

oh ye

[rapid tendon]

fraction

[jagged mesa]

but how do u plot a fraction

[rapid tendon]

just find 1/3 of one box

lol

if the dimensions is same for x and y

[hybrid saffron]

estimate or eyeball it

it doesn't have to be precise

[rapid tendon]

ya

its just a rough sketch with exact intercepts u will be fine

you also need to know the properties of exponential graphs to plot properly

[jagged mesa]

alr

so could u show me the graph

of it

[hybrid saffron]

do not have papel

[rapid tendon]

can use desmos

[rapid tendon]

sure

[jagged mesa]

ok

[jagged mesa]

how the hll

hell

oh

0.333 is just 3?

or

[rapid tendon]

oh ye his graph is better

im on phone

[rapid tendon]

0.333333 is 1/3

[jagged mesa]

sorry

i was hungry lol

[jagged mesa]

i sitll dont know were id graph that

[rapid tendon]

a third from 1

[jagged mesa]

oh

[rapid tendon]

like

[jagged mesa]

so above

or

under

[rapid tendon]

just split the box into 3 squares

[jagged mesa]

ohh

[rapid tendon]

and its in the first box

like that

[jagged mesa]

makes sense

alrr

theres more examples

wait

[hybrid saffron]

you could also eyeball the halfway point of a box

[jagged mesa]

what about 0.1111

[hybrid saffron]

slightly above 0

[rapid tendon]

0.11111..=x

[jagged mesa]

ok

[hybrid saffron]

again, just eyeball it

[jagged mesa]

alr

[rapid tendon]

10x=1.11111

9x=1

x=1/9

[hybrid saffron]

1/0 goes wild

[rapid tendon]

so 0.11111 is 1/9

[rapid tendon]

lmaoo i did a double take i was confused

[rapid tendon]

so 1 9th of the box

[jagged mesa]

ok im gon get more stuff

alr so

[rapid tendon]

modelling

with quadratics

fun

[jagged mesa]

whats tahthahtaht

[rapid tendon]

the topic

[rapid tendon]

use ur calc

[jagged mesa]

alr

i got

130

90

70

and 70

[rapid tendon]

plot the graph

idk if its right cuz im on phone but if u used graph right u will be right

[jagged mesa]

wait i ned a pen

alr got one

[rapid tendon]

kay

[jagged mesa]

alr done

[rapid tendon]

describe the graph to me when ur done

is it a u

or a n

shape

[jagged mesa]

oh

i js plotted like

(0,130

[rapid tendon]

join the dots

[jagged mesa]

(1,90)

[rapid tendon]

in a curve

[jagged mesa]

(2,70)

and (3,70)

[rapid tendon]

join dots

[jagged mesa]

well i guess a u shape

but its not complete

[rapid tendon]

yes

ur right

[rapid tendon]

u see how its positive 10 x^2

its a u

[jagged mesa]

oh

[rapid tendon]

if it was -10x^2 itl be a n

[jagged mesa]

yes

alr so look

this is what i need to learn

algebra

co ordinate geometry

probablity

sequences and series (patterns)

functions

sets

[rapid tendon]

ik a website w some if these

called cognito

[jagged mesa]

ill check it

one sec

lets do more of the things

wait

what does it mean by estimate the height of the water at its lowest point

would it be 70

[rapid tendon]

complete the square

or differentiate

to find the minima point

(turning point)

if you dont know these i can send a video

https://youtu.be/ov3r4hXBU98?si=Ml4Cd9kXaecPSgAT

[jagged mesa]

alr

lemmeee se

ohh

@rapid tendon i think i understand no

now

could u give me one so i can do

also is that another method for quadratics

theres 2 right?

split

and that?

[rapid tendon]

there is multiple

one is the method where you find factors etc

one is quadratic formula

the other is completing the square

my personal favourite

find the turning point of this graph

[jagged mesa]

turning point is just the square yes

im ean

square method @rapid tendon

btw

i gtg for a lil

so bye

[rapid tendon]

cya

$y=x^{2}-x-6$

[naive grotto]

Jam

[rapid tendon]

do this when you are back

cmoplete the square for turning point

for a challenge you can try

$y=2x^{2}-4x-7$

[naive grotto]

Jam

[jagged mesa]

yo

so what am i do

[rapid tendon]

?

[jagged mesa]

what do i do

like

which one am i doing

@rapid tendon yo

ok ig that

[jagged mesa]

anyways for this i got

(x-2x^2) -11

how do i do these

[hybrid saffron]

what do you think part a is?

[jagged mesa]

well i know it

but i maybe wrong

i think

so its kike

the distance between 1,7

(6)

so 6+7 is 13

so 1,7,13

but isnt the distance between 7-13 the same

[rapid tendon]

use the vid, try it yourself and lmk when you have trouble

[hybrid saffron]

yeah

so its a linear progression

[jagged mesa]

oh

so its always 6?

like

13

19

etc

25

weofkdsfksf

and teacher showed quadratic but i forgot

[hybrid saffron]

yeah

[jagged mesa]

all i know is u kinda make ur own

[hybrid saffron]

quadratic is double difference

[jagged mesa]

(x-2x^2) -11

[hybrid saffron]

so you can have double difference of one but single difference of 6

[jagged mesa]

so could u do it for me rq?

js so i can see

@hybrid saffron yo lol

[hybrid saffron]

sry

[rapid tendon]

x^2 - x -6=0
(x-0.5)^2-0.25-6=0
(x-0.5)^2-6.25=0

turning point at

(0.5, -6.25)

@jagged mesa

the 0.5 is from the half of coefficient of x

which is -1

so the thing in the bracket is -0.5

half of -1

[jagged mesa]

what how

anyways ig we can do that tomorrow

we can do number patterns rn

@rapid tendon

i can do linear but idk how to do quadratic

[rapid tendon]

difference between 1 and 7 is 6

2nd difference must be same for it to be quadratic iirc

[jagged mesa]

wym

ok so how do i do quadratic

[jagged mesa]

@rapid tendon

hello?

[rapid tendon]

hi

1,7, -,-,-

so

2nd difference must be same

so we could do

1,7,15,25,37

first difference
6 8 10 12

second 2

second difference = 2a

first term of first difference = 3a+b

first term = a+b+c

so

a=1

b=6

-6 = c

n^2 +6n -6

have you learnt anything like this in school

[jagged mesa]

no

dw we can do all tomorrow

[jagged mesa]

@rapid tendon

hi

i need some help

[hybrid saffron]

hi

send problems

ill be there shortly

[jagged mesa]

alr

so

"D is a point not shown"

"D is the image of the point B under "Central symmetry" in the point P.

Plot and label the point D on the diagram above and join the points A,B,C and D to form the quadrilateral ABCD

A = (-1,1)

C = (5,4)

B = (4,1)

P = (3,3)

[hybrid saffron]

oh.

[jagged mesa]

what

deadass if i dont learn everything today im cooked

[hybrid saffron]

give me ~30 minutes

[jagged mesa]

i maybe cooked

ok though

[jagged mesa]

its been 30 mins

[hybrid saffron]

oops

[jagged mesa]

yo

[hybrid saffron]

yeah

i have too much work to do

[jagged mesa]

oh ok mbb

[hybrid saffron]

sry

ill try later

[jagged mesa]

im prolly cooked for the exam but ty 🙏

no worries

[rapid tendon]

sry i was doing homework

[hybrid saffron]

am back

and ready to attac

[jagged mesa]

oof

ill study tmrw

but the tests on tues

[rapid tendon]

il be free today

to help

i just have a lot of work piled up with deadlines coming up but ive done most of it so il be free sorta

[keen lintel]

h

[jagged mesa]

alr bet

[keen lintel]

you study?

[jagged mesa]

yes but not rn

i need to workout n eat stuff

[keen lintel]

what studying method you use

[jagged mesa]

just do shit tbh

and learn how to do it

[tired otter]

Hi, I would suggest to make a new post if you need help on new problems

Where is the poster?

[rapid tendon]

feel free to ping when u need help

[tired otter]

No, for real, make another post

there's like 20 people on this post and it has at least 4k messages

@jagged mesa @jagged mesa I ask you to close this post and make another if you have another question

[jagged mesa]

you suggested i decline sorry

theres literally no problem with this "most impossible" is undefined it could be a discussion

i have an exam tomorrow buddy atleast wait till then.

[tired otter]

#math-discussion #1018223258228760617

[jagged mesa]

generals

[tired otter]

That's fine

[jagged mesa]

and mods etc didnt have a problem with this

[jagged mesa]

ok then

[tired otter]

I don't mind waiting, I am just kindly asking you to make another if you need more help

but you can always come back to this one if you need to check

[jagged mesa]

ye i just got alot to do so

[tired otter]

if you have the link, you can access it even if it is closed

[jagged mesa]

tomorrow then but as of now ill still use this

[tired otter]

I'll hold you to it

[hybrid saffron]

so, are you ready to start?

[jagged mesa]

very soon

[hybrid saffron]

alright, now?

[jagged mesa]

im ready now

[jagged mesa]

e

[hybrid saffron]

i’m in class

[jagged mesa]

oh

when will u be finished

[hybrid saffron]

around 4 pm

[jagged mesa]

oh 2 hours

thats good then

[hybrid saffron]

mhm

alright

[jagged mesa]

i js have to go over everything

mostly algebra def arithmetic and i think yk sets so yee

functions a lil aswell and probability

e_e

alr bye

[rapid tendon]

i am too send any qs u wanna work on

[jagged mesa]

ok

this prob wont be in the test but eh

lets do it

"400 sterling, convert this money into us dollars. Euro = £0.90

Euro = $1.17

Work out how many dollars you can get with £400 sterling

give your answer to the nearest cent

[jagged mesa]

yo

[rapid tendon]

sup

[rapid tendon]

so how far do u understand this q

show me your steps/thought process

or answer

[jagged mesa]

i dont really have one

im guessing smth with decimals

or division @rapid tendon

[rapid tendon]

so the question is £400 to dollars
1 Eur = 0.9GBP
1 Eur = $1.17

we can see that

£0.9 = $1.17

£1 = 1.17/0.9

as you divide both sides by 0.9

do you understand so far

@jagged mesa

[jagged mesa]

yo

[jagged mesa]

ye i see

[rapid tendon]

alright

now

if £1 = 1.17/0.9

what would £400 be

[jagged mesa]

e

hm

i got 444.9

oh wia

i divived w 0.9

341.88 @rapid tendon

[rapid tendon]

is that 400*1.17/0.9

if so ur right

[jagged mesa]

its 400 divided by 1.17

[rapid tendon]

nah

oky

lets try thus

if

A=2B

what is 3A equal to?

[jagged mesa]

9b

or possibly 9b^3

[rapid tendon]

nope

remember, 3A means 3*A

you need to understand properties of equations to do stuff like exchange rates

for an equation such as A=B

kA = kB

k can be any number

like

if A=B

100A = 100B

so il ask again

if

£1 = 1.17/0.9 dollars

what would £400 be equal to?

in dollars

[jagged mesa]

wym

like with the a and b stuff

[rapid tendon]

A and B are like sides of an equation

if you would rather have numbers

10x = 1

[jagged mesa]

ye ok

[rapid tendon]

100x = 10

i multiplied both sides by 10

[jagged mesa]

but money is different is it not

[rapid tendon]

nah

if £1 is $2

rhen £2=$4

[jagged mesa]

ok

so

[rapid tendon]

£100 = 200$

[jagged mesa]

ye

[rapid tendon]

thats wrong cuz exchange rates arent like that btw

it was just an example

[jagged mesa]

ye

so £1=1.17 dollars

?

or is it 0.9 dollars

yo?

[rapid tendon]

£0.9 = $1.17

[jagged mesa]

ohh ok

[rapid tendon]

how would you find £1 from this

rate for £1

to dollars

[jagged mesa]

find £0.1 ?

e

[rapid tendon]

why £0.1

[jagged mesa]

idk i never listend for this lol

cuz then u add 0.1 with 0.9

[rapid tendon]

i mean sure but

you could just

divide both sides by 0.9

£0.9 = $1.17

what do you get when you div by 0.9

both sides

[jagged mesa]

1 = 1.3

[rapid tendon]

whays 400£ then?

[jagged mesa]

OK

ok*

520$

@rapid tendon

[rapid tendon]

yep

well done

[jagged mesa]

yayayayay

can u give me an example of an exchange one

ill try do it

[rapid tendon]

x=3y
y=2z
find 105x in terms of z

try this

[jagged mesa]

ok

but this isnt currency

so its a lil harder

[rapid tendon]

it doesnt matter

currency is in reality just another variable like x or y

[jagged mesa]

ye ig

so

ig x=6z

but how do i get 105x from that

ohhh

no nvm its 105x = ()z

105x(6z)= 630z

i mean

105*

(6z)= 630z

so 105x = 630z

@rapid tendon

[rapid tendon]

yes

perf

[hybrid saffron]

sorry if it’s been too much helping on your end jam, i’ve been extremely busy with school and extracurriculars. i should be free tommorow and maybe a little today

[jagged mesa]

my maths exam is tomorrow

but dw i never really studied before

aslong as i get 50% thats good

i just need to stay in higher level.

[jagged mesa]

alrr

[rapid tendon]

allg i havent been on much in a while tbh

[rapid tendon]

gl

[rapid tendon]

howd it go

[jagged mesa]

yo

it was actually alrr no struggle but i prolly failed all of algebra questions lolol

i think i did good in probability

co ordinate geometry

functions 50/50

idk wtf Tn is.
