Question

Do any of you go to CA and take Algrebra? I NEED HELP!

Answer 1

@onedirection822 can you fan me? it says i can't message you back unless you do.

Answer 2

What's the question?

Answer 3

@Peasant1 actually questions i really suck at algebra .__.

Answer 4

Post the questions here so we can help you :]

Answer 5

Yeah. Algebra comes pretty easy to me so if you post the question or a screen shot we could help. :)

Answer 6

ok hold on (:

Answer 7

Alright!

Answer 8

OK so, the way to solve this is quite simple.

Answer 9

i dont get where to start at

Answer 10

For the first part of the question we'll use -4x+3y=-12

Answer 11

Quick question, do you have a graphing calculator?

Answer 12

no i do not D:

Answer 13

That stinks... Well... I do. maybe I could help explain it in a way you could understand... first lets get the first equation in a way we can use it.

Answer 14

so, with -4x + 3y = -12 we need to get y on one side by itself.

Answer 15

so dont you have to multiply -4x by 0?

Answer 16

no

Answer 17

we have to add 4 x to both sides. We then get 3y=4x-12

Answer 18

Make sense?

Answer 19

yeah i get it (:

Answer 20

ok so now divide 3 by both sides so that you get y by itself. It should look like this: y = 4x/3 - 4 Still with me?

Answer 21

ok got it .

Answer 22

Ok now, leave that equation like it is. It's ready to be used but now we have to get the other one ready. -2x + 3y = -18

Answer 23

We need to get y by itself again. What do we do first?

Answer 24

we move the -2x, which i got y=2x/3-6?

Answer 25

Great job! Now, we have to graph those equations. That's going to be hard for you meaning you don't have a graphing calculator.

Answer 26

Peasant1, can I suggest something?

Answer 27

sure.

Answer 28

You have:
y = 4x/3 - 4
y = 2x/3 - 6

If you do,
4x/3 - 4 = 2x/3 - 6

You will find the point where the two functions intersect. After that, you only have to search that point on the options.

Answer 29

haha I completely overlooked that method. lol I always do it this way but that way works just as well... :P

Answer 30

:) Solving the equation, you will find x = -3.

y = 4x/3 - 4
y = 4*-3/3 - 4 = -4 - 4 = -8

The intersection point is (-3, -8).

Letter B.

Answer 31

omg thank you i get it now (:

Answer 32

haha yup the way I got it was by graphing the two equations on my calc.

Answer 33

haha Awesome @lunitaboo ! See it's not too hard. ;)

Answer 34

ha thanks ! you guys are nice btw (:

Answer 35

you're welcome :]

Answer 36

Your welcome!
