stuck timberBOT
minor shell
#

i need help with 5,6,7

#

<@&286206848099549185>

#

u gotta graph thise

#

i dont get this shit

sterile sierra
#

Start graphing the constraints

#

Do you know how to plot those four inequalities?

minor shell
#

for number 5 he made us graph@like this

sterile sierra
#

Yeah you need to graph one by one those lines

#

Solve for y each of them

#

And plot them

minor shell
#

i dont get why he didnt graph x>=0 or y>=0

sterile sierra
#

He did

minor shell
#

wait does Y js go up nd down

#

and x is side to side

sterile sierra
#

Since he only took the first quadrant

sterile sierra
minor shell
#

x <=5 and y<=5 which is

sterile sierra
#

Once you plot it, you can evaluate each vertex and check the value of k

minor shell
#

5,0 0,5

minor shell
sterile sierra
#

We are on the first question

minor shell
#

yeah

#

im on that too

sterile sierra
minor shell
#

but my points are on (0,5) (5,0)

#

and then idk how he got 2.5, 0

sterile sierra
#

Once you got the points

#

Can you show me your graph?

minor shell
#

2x + y >= 5

sterile sierra
#

Yeah plot that

minor shell
#

do i put that into y = mx+b

sterile sierra
#

Yeah

minor shell
#

y >= -2/1x + 5

sterile sierra
#

Try again

minor shell
#

y >= -2x + 5

#

No?

sterile sierra
#

Y>=5-2x

#

Yeah

minor shell
#

okay nd then i put 5 on the x axis right

#

or is it Y

sterile sierra
#

First plot y=5-2x

minor shell
#

how do i do@that tho

#

i obviosuly need points to plot those numbers

#

Or do i do rise over run

sterile sierra
#

Yeah just make X=0

minor shell
#

so u substitute x as 0 inside

#

Instead*

sterile sierra
#

Yeah

#

To get one point

minor shell
#

Y = 5

#

holy shit im so confused what this dude taight me

sterile sierra
#

Cool your have a point now

#

(0,5)

minor shell
#

i get that but

#

he has a point at 2.5 and 0

sterile sierra
#

Now make y=0

minor shell
#

for x axis

#

and he only has 3 points

#

like 3 dots to make the shape

sterile sierra
sterile sierra
minor shell
#

-2x = 5

sterile sierra
#

Try again

minor shell
#

x = -5/2

#

5 over 2 negative

sterile sierra
#

No negative

minor shell
#

how so

#

oh wait

#

ur right

#

yeah

sterile sierra
#

X=5/2

minor shell
#

but now i basically have what 5 dots on thr chart

sterile sierra
#

No

#

You have two dots so far

minor shell
#

wb the x>=0 y>=0

sterile sierra
#

(0,5) and (2.5,0)

sterile sierra
minor shell
#

Okay

sterile sierra
#

Plot that line

minor shell
#

Yeah got that

sterile sierra
minor shell
#

what is a quadrant

#

like one piece

#

in rhe 4

#

the

#

this dude doesnt explain stuff nd throws quizs out

#

so kinda dont know anything

sterile sierra
#

Ok let me show you

#

There are four

minor shell
#

yeah

sterile sierra
#

You need to know plot the other equation

#

Doing the same

minor shell
#

so how do i know which quadrant im supoose to use

sterile sierra
#

X=0 then y=0

minor shell
#

Yeah

sterile sierra
minor shell
#

so first quadrant is top left?

minor shell
#

No?

sterile sierra
#

Top right

minor shell
#

top right

#

sirry

#

he still used the bottom left one

#

for some reason

#

Does that matter

sterile sierra
#

One sec

minor shell
sterile sierra
#

He did it ok look at the values of X and y

#

They are all positive

minor shell
#

i js dont get the quadrant stuff which got me confused cz u said if the values r positive such as 0,0 then u use top right bix?

#

or hows it work

sterile sierra
#

Let me send you a voice

#

Explaining

minor shell
#

Okay

#

sorry not the best learner js confused as hell

sterile sierra
#

Just did it probably to have more space in the paper

#

The number is not negative in that question

minor shell
#

I may need help with number 6 in about 20 minutes

#

If youll still be on

sterile sierra
#

Yeah they are all using the same method to solve

minor shell
#

If im stuck

#

Ill lyk

#

Afd me

#

Thank u bro

#

@sterile sierra

#

hey

#

so you know how we got 5,0 0,5 and 2.5, 0

#

(5,0) (0,5) (2.5,0)

sterile sierra
#

Yeah

minor shell
#

why dont i solve 2x+y>=5

#

and isolate twice

#

like

#

i solfed for x right i plugfed in 0

#

and got y>=5

#

why dont i do the same for 2x

#

2x >=5

#

wair wtf

#

oh is it cz y >=5 is already a point

#

from x+y>=5

#

ykwim

#

@sterile sierra

sterile sierra
#

Are you trying to solve the second one now?

minor shell
#

no the same first one

#

from@one equation u get two dots

#

yk

#

why dont i dot all 4 why do we dot only 3

#

is it cz y>=5 is alr a point

sterile sierra
#

You need to dot 4

#

For the first equation

#

Unless they are negative values . Since those are excluded
