I need help please and thank you i need help with five questions if you can help please do i need to get my percents up to 85% by the end of the day and i have it at 65% as of now i will fan and medal

OpenStudy (shelbywyatt):

with what

OpenStudy (jpharper12345678cars):

OpenStudy (jpharper12345678cars):

that

OpenStudy (erak):

Okay, let's try eliminating the one that doesn't look right by looking at the slope.

OpenStudy (jpharper12345678cars):

i think the answer is c?

RhondaSommer (rhondasommer):

\[y=mx+b\]\[m=slope\]\[replace~slope~~for~m~in~the~equation\]

OpenStudy (erak):

Yes the answer is C

OpenStudy (jpharper12345678cars):

can you help with more please @Erak

OpenStudy (jpharper12345678cars):

OpenStudy (jpharper12345678cars):

there we are

OpenStudy (erak):

It'd be C, because when in that bracket, (x-3), x actually = 3

OpenStudy (jpharper12345678cars):

ok cool 3 more

OpenStudy (jpharper12345678cars):

OpenStudy (jpharper12345678cars):

@Erak

OpenStudy (erak):

Look at the slope, if the 1/2 is negative, it's going down from left to right. If it's positive, the line should go up left to right. Which ones can you cross out?

OpenStudy (jpharper12345678cars):

b

OpenStudy (erak):

B is an answer but there should be one more.

OpenStudy (jpharper12345678cars):

d?

OpenStudy (jpharper12345678cars):

let me geusss im stupid right?

OpenStudy (erak):

Nah you're right

OpenStudy (jpharper12345678cars):

OpenStudy (erak):

It's basically finding the x and y values that will make both sides of the equations equal, and yeah no problem I'm just eating

OpenStudy (jpharper12345678cars):

OpenStudy (erak):

The slope is correct, but the b value in y=mx+b is not. The b value is given when x = 0.

OpenStudy (jpharper12345678cars):

so a?

OpenStudy (erak):

Look at how much the cost increases per 50 page increase, and subtract that change.

OpenStudy (erak):

Yeah, because it increases 0.80 each time, so 1.75 - 0.8 would give you 0.95

OpenStudy (jpharper12345678cars):

OpenStudy (jpharper12345678cars):

jo

OpenStudy (jpharper12345678cars):

i hope i pass @Erak

OpenStudy (jpharper12345678cars):

this is the last qestion

OpenStudy (erak):

So "C" basically says the line exists at (-4,-2), but if you look, it doesn't. Which one might it be?

OpenStudy (jpharper12345678cars):

d?

OpenStudy (jpharper12345678cars):

////?????

OpenStudy (jpharper12345678cars):

please hurry?

OpenStudy (jpharper12345678cars):

@Erak

OpenStudy (jpharper12345678cars):

my sessions about to time out this aint worth it im still at 65% and its been an hour

OpenStudy (jpharper12345678cars):

i need to work at a faster paste

OpenStudy (erak):

It would be A because it exists at -4 and 2. Sorry I had something come up

OpenStudy (jpharper12345678cars):

its fine i just dont want to fall math

OpenStudy (mrnood):

is it YOUR score that oyu are hoping to raise - or are you just taking @Erak 's score WHY are you still at 65 with 1 hour to go if oyuy dont want to fail?

OpenStudy (jpharper12345678cars):

omg @Erak I LOVE YOU YOU WANNA KNOW WHY

OpenStudy (erak):

Well honestly MrNood is right. You're going to have another examination and if you can't do it on your own, it'll be hard to save your mark.

OpenStudy (jpharper12345678cars):

can you help with more @Erak
