k
Do you know what to do from there?
ok so I have $\frac{\log\left(2^{3x-1}\right)}{\log\left(2^{4x-2}\right)}=\log16$
You can take log_2
what should I do
Bongo
ok
No that's wrong
Don't take log_10
ok so I divide by log 2
Why divide?
$\frac{\log_{2}\left(2^{3x-1}\right)}{\log_{2}\left(2^{4x-2}\right)}=\log_{2}16$
dldh06
Change the base for what?
yes I did the change of base formula
Where $$\log_{b}a = \frac{\log_{x}a}{\log_{x}b}$$
dldh06
Where x can be 10
yeah
so $\ \frac{\log_{2}\left(2^{3x-1}\right)}{\log_{2}\left(2^{4x-2}\right)}=\frac{\frac{\log\left(2^{3x-1}\right)}{\log2}}{\frac{\log\left(2^{4x-2}\right)}{\log2}}$ or no
Bongo
or did I mess up
ok what did I need
Recall that rule 6, $$\log_{b}(b^k) = k$$
dldh06
yeah you told me
mb didnt see this was in use
so its just:$\frac{3x-1}{4x-2}=\frac{\log16}{\log2}$
Bongo
k
Think you got the rest?
stuck on this pr oblem for 3 hours man š¦
Yes
I will try
ok I have an issue
first of all is this process right:
$$\frac{3x-1}{4x-2}=\frac{\log16}{\log2}$$
$$\frac{3x-1}{4x-2}=4$$
$$3x-1=4\left(4x-2\right)$$
$$3x-1=16x-8$$
$$-13x-1=-8$$
$$-13x=-7$$
Bongo
Yeah, looks correct so far
ok
so when I substitute into this I get different results:
like its saying its not right
so what mistake have I done
,calc 7/13
Result:
0.53846153846154
,w solve \frac{2^{3x-1}}{2^{4x-2}}=16 for reals
I dont th ink Your meant to give me the answer? or do you have 2
Just using the bot to check your answer
ok so my answer is right
I'm checking
should I just skip this question?
Btw this was the original question: $\frac{2^{3x-1}}{4^{2x-1}}=16$ but I made 2 the base so its easier
Bongo
you agree this is like impossible 2 solve
It's possible
so what mistake did I do
ok
,w 4^{2x-1} = 2^{4x-2}
wait nevermind
,w log_{2}16
I accidentally found the answer
I checked it was -3
I just put in all values
oops guess I cheated...
,w \frac{3x-1}{4x-2} = 4
,w \frac{2^{3x-1}}{4^{2x-1}}=16
Huh says -3
this is wrong
,w \frac{2^{3x-1}}{2^{4x-2}}=16
it shouldn't be 3x-1/4x-2
,w \frac{3x-1}{4x-2}=log_{2}16
this is the most confusing
if anyone knows why the answer is -3 please dm me
So I was assuming raising both the numerator and denominator by $$log_2$$ was valid but I think $$\log_2{\frac{2^{3x-1}}}{2^{4x-2}} = \log_{2}16$$
Is the way
k
ok I will fix this error for you
here is the corret code: $\log_{2}\frac{2^{3x-1}}{2^{4x-2}}=\log_{2}16$
Bongo
dldh06
Compile Error! Click the
reaction for more information.
(You may edit your message to recompile.)
is this right or no
Yeah, tha way
you messed up when you assume log(a/b)=log(a)/log(b)
how do i solve this help pls i am dumb, i tried factoring the terms but it led to a very wrong answer
You wanna check this out for me?
Channel busy
ok
for one second I thought I found a black hole in mathematics jk
jkjk
idk, i just scrolled thru it, it looks like you have made that assumption
Made this assumption for the LHS
To get this
yeah, so that is wrong then
ok so the real answer is:
$\frac{\log\left(\frac{2^{3x-1}}{2^{4x-2}}\right)}{\log2}=\frac{\log16}{\log2}=\frac{2^{3x-1}}{2^{2\left(2x-1\right)}}=16$
log(a/b) != log(a)/log(b) in general
Bongo
i mean i you can continue with that path
log(a/b)=log(a)-log(b)
So it should have been this? waler
can someone help me with this
Channel busy
sorry sorry ill wait
oh ok I do the
i thought he was done cause he said good job guys
Bongo
Use log_2
If you use log_2, you will have 3x - 1 -(4x - 2) = 4
How?
just look at desmos:
i mean technically this equation is true
but why do you have to make it hard for yourself?
Technically it's true, but base 2 will make it easier
I already did base 2 here no? $\frac{\log\left(\frac{2^{3x-1}}{2^{4x-2}}\right)}{\log2}=\frac{\log16}{\log2}$
Bongo
Because things cancel
it will still be a linear equation but now you have all of these "not so nice" numbers to deal with
ok
Definitely unnecessary
$\log_{2}2^{3x-1}-\log_{2}2^{4x-2}=\log_{2}16 \implies (3x-1)-(4x-2) = \log_{2}16$
dldh06
$$(3x-1)+(-4x+2) = 4 \implies -x + 1 = 4$$
dldh06
this is too complex for me
It's not though
Find the coordinates of the point P (x {r}, y {r}) that divides the segment A (3, - 1), B (0, - 2) at a ratio r = 1/3
Can someone help me with this?
I accidentally assumed that log_2 goes to both num and dem
ok I will trya nd get it
Ah?
$\log_{2}\frac{2^{3x-1}}{2^{4x-2}}=\log_{2}16$
ok
dldh06
wait so is this right $\log_{2}2^{3x-1}-\log_{2}2^{4x-2}=\log_{2}16$
Bongo
Yes, then it's that
Does that make sense so far?
ok
so it simplify to: $\left(3x-1\cdot\log_{2}2\right)-\left(4x-2\log_{2}2\right)=\log_{2}16$
Bongo
k I got it from here
Those log_2{2} cancel to be 1
Bongo
$\left(3x-1\right)-\left(4x-2\right)=\frac{\log_{10}16}{\log_{10}2}$
You meant 10
Not 2
dldh06
It doesn't matter, but can your calculator do $\frac{\log_{2}16}{\log_{2}2}$?
dldh06
Or is the log on your calculator base 10?
Got it now?
Didn't mean to confuse you by assuming that log_2 goes in both the numerator and denominator
OK thanks
yeah thought maths was wrong for a second
how hard is this would yo say
is this fitting for grade 11 or no
10 is the entire bottom side and b is only the right part
how can i find the side lengths?
It's not too hard, I just applied the concept wrong by accident
Wait is this channel occupied?
btw the two lines that intersect the triangle are angle bisectors
3.The quotient of a number
and three is equal to twice
the difference of the square
root of the number and the
number squared.
Translate into algebraic equation
Please anyone
quotient = divide
difference = subtract
just read left to right
also the channel is occupied
and dont crosspost
Oh ok
I need help
I want to find a, b, and c.
Sorry the channel is already taken there are other channels
i don't understand what this question is asking can someone help please
SubGui
@barren jacinth
hello can somebody help me with logic?
people can't know if they can help without knowing the problem
dont ask to ask
server lemma
Yep, and XY's
Sketch the graph of y=f(x) and y =fā1(x) on the same set of axes on the graph given. (eā1= 0.3679).
does anyone know where to even start?
clearly not enough info
since f(x) is not defined at all
Consider the function defined byf(x) = 2e(xā1)+ 2
this is homework due in next week, don't understand it at all ;/
is that the function, or a fucked up typing?
f(x)=2e^(x-1)+2
ok, well you know the asymptote, then just pick some points to get the general shape
Could I get quick help on two easy questions Iām too dumb to figure out please?

Iāll just send a picture of the page. Iām struggling with 15 and 16. In 15 my answer doesnāt match the answer key at all, and on 16 the closest I can get to the answer key is 11
Ik I could just copy from the answer key, but that doesnāt seem right
In 16 u can further simplify 7x49
I did I just ran out of space you can see it at the top beside it
7x7²=7³ not 7²
Oh my god I feel so dumb
My brain is not functioning ty
Do you know about 15?
Oh wait no, I tried that. I need the sum of the numbers to equal 12
Does angle have effect on distance?
Wait no that wouldnāt work anyway
Cause itād equal 343 and the sum of them would be 16
Sum of 2,7,3 is not 16
Where the hell is my brain
How did I get 16
Wait whereād 3 come from
I canāt use 3
343=7³
what are the three consecutive prime odd numbers being talked about?
The question is all the information we got for it I have no idea, idk why the answer key has 105 when 1 and 0 arnt even prime
So Iām hella confused
then why did you even write 357 as your answer?
for 15
how did you come up with that idea?
Could it be 105 is the product of a,b and c?
...
Cause theyāre all prime numbers, and theyre consecutive odd numbers that are prime
you mean 3, 5, and 7 are prime numbers that are consecutive odd numbers
357 is divisible by 3
not 357.
so what is the product of 3,5, and 7?
definitely not 357.
the question is asking for the product of a,b, and c
not for a,b, and c themselves
Huh it never asked for the product Iām so confused
Thatās what I just said but ok
abc=a x b x c
I need to learn the basics again I forgot that would mean multiplying them
God my brain hurts
abc is literally the product of a,b, and c
not a,b, and c themselves
so when someone tells you
abc = 15
it means that the product of a,b, and c is 15
Sorry you have to answer my dumb questions Iām tired as hell rn and canāt think
the answer would just be (3)(5)(7)
multiply 3,5, and 7 together
that's what the question is asking for
Alright got that, what was 16 again?
3,5, and 7 are the three prime, consecutive odd numbers
I didnāt fully get 16 still
7 little 3, but I canāt have 3 cause itās not one of the prime factors
7^3, u mean.
Yeah I wasnāt sure how you right it like that
which totally does not say that 3 is a prime factor.
7^3 means that you take 7 and multiply it by itself 2 times
you should look up what the FTA is
FTA is fundamental theorem of arithmetic
Oh my god does it not have to be the prime factors of 686
Could it have been any prime factor
Ty guys for the help, I appreciate you dealing with my tired and stupid mind
Itās almost impossible to do math when your tired as hell and your family is being annoyingly loud
can someone help me?
with what?
math
ok send it
you only need to send it in one channel
ok jus a sec
can anyone help me start off i know its a formula you have to use but im not sure what to plug in
<@&286206848099549185>
there
Do you know how to calculate the mean of a set of values?
i dont
HELP
Do you know what a mean is?
oh ez
@balmy patrol the mean is the average
yeah ok
And thus, you should find the sum of all values, and divide it by the number of values
If x is the number of values and n is the sum of the values then it is simply n/x
Do you understand?
No worries
@alpine sable and for the median is it the same thing

The median is the middle value
median is the middle number in the list ordered from lowest to the highest
Literally just the value that is in the center
You dont have to calculate anyhting
....BRUH
oh i see
lol
help me plss
What are you struggling with?
Look at the grid
is that easy for u, jus asking?
What you are looking at is a cartesian plane, the x axis is the horizontal bolded lone, and the y axis is the vertical bolded line
Do you see how there are notches on each axis?
They each represent a number, and the number increases in value by 1 for each notch as they get further away from the center (known as the origin)
Yes
same
but in gr.8
Use this to help you
I'm here
What dont you understand
lol
The x value is the first value in the ordered pair, followed by the y
^
for Part A
how do i know?
The answer is 3,6
It's what you think it is, find the x and y value of each point
I gave you a diagram
wym x y?
X axis and y axis
I explained that here
i mean
How did you get -3,4
for b?
not really math but im just confused why you would add 2CE to both sides instead of just keep it as 1
i understand adding 2h because we have h2o on the left side
yay k
i got a question
imma figure out the rest
Did you count the atoms on each side?
i need help with functions
well ya but wouldnt 2ce just cancel out?
simplify to just ce
anyone know why you are supposed to put 2ce?
OH I GOT IT
dwwwww
ok im done
guys i don't get c?
for part a?
yee
Its exactly the same
- c
Just with different values
^^
What dont you understand
Just send the question 
Wdym "starting from"

so it says given the graph of y=f(x) to the right match each transformed function to the apropriate graph but when i put theoriginal function in desmos it doesnt work
How did you get that
idk
its like a half circle then a triangle kinda graph its weird
I need to know so I can see where you went wrong
how to explain it
...
send the picture
idk
Look at the picture vorex sent and then you just have to max the point to the values
is it
wait holy sh1t i figured it out
So its in the bottom righ quadrant, so the x value will be positive, and the y negative
1, -2?
š¦¦
Yeah
yayayayyayayayyayay
Simple interest formula?
ok so
A= (3,6), B= (-4,6) C= (1,-2), D=(0,0) E=-(2,-3)
??
r those correct?? @vivid anvil
np
So I'd have to scroll
B is not correct
oh wait
LOL
how?
-5, 6?
You confused B with F
For the 1,000,000th time
loll
B= (-4,6) is incorrect because that coordinate is F
that doesn't help me at all cuz
Do you apparently not know your alphabet?
i do
Where is B?
Where is the letter B?
6
Left or right of the origin?
right
Yet you said B = (-4, 6)
is it 4, -6??
@elfin fiber do you know what the letter B looks like
No
WYM
On your paper, circle the letter B
k done

say for example theyre was a parent function f(x) what would happen if you did {f(x)} and absolute valued it what would happen to the graph
This channel is busy
wym bro
sry bro
You have a solid black line and gray line, where is B?
@elfin fiber do you have glaucoma
there is no gray line?
I think so
Yes there is
The gray lines are the thin lines
There's gray and black lines
Is B on a thick line or thin line
is it 0, 6??
Thick vs thin lines
Yes, that's Point B
omg
@wary stream the numbers appear wrong on the x axis
LOL
The 5 is not in the correct position
Can you count?
Those are the even values
Shown
No odd listed
0 is in the the middle?
How did you get 6?
bc there's 5 there?
There's not a 5 printed on the paper?
yeahh
@elfin fiber treat that 5 as though it was a 6
well then 7??
Can you send a close up of just that grid?
alr
It definetly looks like a 5
I mean the paper is blurry
Even if you change it to a 7, it's still not correct
fr
Still looks like a 5
Maybe nao cant see images
š
Thats the only explanation
......
No
-1,7?
lollll
What direction is left and right?
@elfin fiber x value preceeds the y value
Like coordinate
what
Is left and right, the x or y value?
@elfin fiber the x value comes before the y value
x
So your answer (0, 7), is 0 the x or y?
Lol are you ok?
no
@vivid anvil
Coordinates are (x, y), corrct?
i hate math
Wtf is -0
yeah
stfu
idk what it is
Read what I am saying
Logically think of your answer (0, 7)
That means x = 0 and y = 7
meaning you traveled 0 in the x and 7 in the y
welll
Does that lead to point B?
no
So what are the coordinates to B?
7,0?
Yes
Yes
ok
š
hello guys
lolll
You are missing a letter here
yeah ik f
anyone here good with differential geometry and transformations?
Don't ask a question here, it's being used
Ask in a different channel
is F (-3, 4)?
Yes
Its the same thing just in reverse
š
-0
You literally find the letter that matches that coordinate pair
Hint: none of the answers involve -0
LOL
Follow the given coordinates, find letter, what's so hard about that?
Hey you forgot to quote
yeah but the letters
ā-0ā - 2021, nao<3
What about the letters
but helpp mee
how do i know
Still stuck with part 2 question A?
that is so hard
yeah
Dude just use what I gave you
Are we being trolled
Itās extremely helpful
how?

It's on the paper
exactly
The letters are on the paper
You just find which letter resides at the coordinates given
what?
Itās like what you did in part A
Which letter is at -7,3?
t?
Yes
How many human beings does it take to help a nao
Too many
3
@elfin fiber do you understand
kinda
You should just guess, you honestly have a 1/6 chance of getting it correct
Or you should pay attention in class
this is the review thing
Because you just count
teacher didn't tell us
Channel busy
ok
.....it's literally been like a week in school
this is jus a review of how much we alr know
but i know nothing sooo
š
If it's review you should know it
It's a basic concept
nooo
For not knowing how to ācountā?
It's literally counting
Left/right, then up/down
š
Everyone hates math but itās required in high school
You can never avoid math
Youāre in grade 8 right?
The coordinate plane is a two-dimension surface formed by two number lines. One number line is horizontal and is called the x-axis. The other number line is vertical number line and is called the y-axis. The two axes meet at a point called the origin. We can use the coordinate plane to graph points, lines, and more.
mhm
Did you give up on 2?
i did it
ok
Or what did you get
The question is so far back
Question 3, you forgot c, g, and you have one incorrect
Is it?
is d w?
Is it?
i don't think so
yeah
Are you sure?
Positive?
Great \s
where?
Watch this
Lol is that marked as sixth grade math?
I did that in grade 6 too
But my grade 7 class did it as well
š
yeah good for u
š
Because it will help
For me we learned very basic planes in 4th but didnāt learn it until later
You still stuck on A?
well it's due tmrw
What do you need help with? How coordinate planes work?
Mainly counting and the alphabet
If you reread this all
loll
Like a letter for another
...
What donāt you get? (If you want to ignore me, feel free to)
Ok, so you know how to plot cooprdiniates on the plane?
@fair osprey This was the reply trying to correct point B
That was the paper
Make time, watch video, simple
This is it right?
mhm
If you have time to be getting help on a server, you have time to watch some videos to understand this
videos don't help me
Lol Iām dumb but whatever
i'm dumber
One of the letters looks like P
Khan academy is the best tool to learn
Idk if thatās just me
They teach very well
is x-4=(2/3)y equivalent to (3x-12)/2=y
Idk what you donāt get, but Iāll try to explain how planes work? Maybe itāll help
Wrong person
You already have your own channel, don't barge in
Ooop
lol
All I did was repost the question

lmao didnt see you respond
I'm being serious, make time and watch Khan Academy
You could have finished watching that video after all this time
@elfin fiber
Ona. Coordinate plane, thereās the x and the y axis. When plotting points, you get a cord, usually something like ā8,0ā. The 8 is the x, and 0 is the y. C is horizontal and y is vertical, x comes before y(th8nk run before you jump). There are 4 quadrants, 1,2,3, and 4. (Iām not 100% on the order of them) I think 1 is upper right, and it goes countr clockwise, with 1 being the all positive, 2 being negative x, positive y, 3 being all negatives, 4 being positive x, negetaive y
Does this help?
ok
Wait, nao. Is is the plotting coordinates thatās confusing you, or just getting over whelmed by how many?
As I said, I'm pretty basic counting is confusing them
yeah there's lot
sighs
1
2
3
4
5
6
7
8
9
10
Wait, I have a possible helpful idea
ok
My helpful idea was watch Khan academy
I like your idea
But apparently nao doesn't have time to watch them
Instead they are on a server, getting confused, wasting time when that time could be used watching Khan Academy
Ok well you need to watch both halves of it
@elfin fiber what are the cords to these? Does this help?
I agree
Me too
Like, you donāt use a half assemble house to live in, or a half assembled evice, do you?
Just watch, nao is going to watch the second half first and then the first half later
A better example, is you don't do half an assignment, do you?
Well I have before
Probably for half credit?
No its because it was on art history
Iām still kinda confused on how nao was confused
We all are still
Nao is a force of nature
We are trying to help
bye
bruh
I am trying to
What do you not understand?
Because you don't comprehend what the people are tell you
yeah cuz i don't get it??
Whereās point A?
work hard to understand it
does that mean you'll jus make fun of me
We are telling you what to do and how to do it yet it goes over your head
and it's cuz i have adhd
same
What specific part do you not understand?
yeah i did what u told me
omg
ik its hard with adhd but its something you need to do
yeah ik
ya know
are you tho?
Wait, how about this. Can you explain how to use coordinate planes?
can anyone help
yeah i'm finished everything accept the last two pages
It took you about 45 minutes to actually watch the video I linked
pls <@&286206848099549185>
Not here, because channel busy
videos don't help me gosh
Also you have to wait at least 15 minutes before pinging helpers
Nao, can you explain how the coordinate planes work?
what are you specifically stuck on
Or, walk us through step by step of how you plotted the ones you did?
whats she tryna do?
Khan academy is really helpful
yeah but i jus don't understand some of them
like which one
or what the ques is saying
yeah
then post the questin
ok
Post the question
k
dld while she does that can you check out question 5 real quick
Nao, maybe try explaining how to get the cords for point A?
Which question?
5
BRO
Plot 5,5 on there. If you can do that, you should be able to do you assignment
It's asking how many spaces left/right and then how many up/down
lmao
k wait
theres no negatives
?
Channel busy
right its only asking how much movement there is on the x and y axis
Question 5, literally says describe how to reach that point
? Use an image editor, and plot it on there that way?
uhhh
describe: give an account in words of (someone or something), including all the relevant characteristics, qualities, or events.
