Question

help me!!

Answer 1

with whettt?

Answer 2

The graph of a system of parallel lines will intersect at exactly 1 point.

Always

Sometimes

Never

Answer 3

never, parallel lines never intersect

Answer 4

@petiteme

Answer 5

im confused would it be sometimes or never?

Answer 6

never. parallel lines NEVER intersect. that's one of their properties

Answer 7

Never :D

Answer 8

Parallel lines never meets.

Answer 9

okay thnx can u guys help with anthoer one?

Answer 10

What is the value of the y variable in the solution to the following system of equations?
3x - 6y = 12
-2x + 3y = 6

-14

24

14

-24

Answer 11

Sure. :D

Answer 12

yea that's correct

Answer 13

okay @petiteme me can u help me the problems above ;D

Answer 14

Do you at least know how to do this?

Answer 15

no im confused like would i use elmintation method?

Answer 16

@petiteme

Answer 17

Yes. Try it. Lemme check your work.

Answer 18

1x + -3y = 18?

Answer 19

did i do it right? @petiteme

Answer 20

I'll brb. I asked @wolfe8 to help ya.

Answer 21

okay @wolfe8 Did i do it right?

Answer 22

Which method do you choose to do?

Answer 23

elimintation

Answer 24

Well if you use elimination then you wouldn't have one of the unknowns anymore so I guess you did it wrong. Since you want y, you should multiply either one of the equations so that the value for x are equal. Give it a try.

Answer 25

like thats what i dont get what would i multiply one of the equations by?

Answer 26

It's totally up to you, but you will want to make one of the unknowns equal in both equations so you can eliminate it. Hence, the name :) Also, if it seems easier for you, you can multiply both equations with a different number each to achieve this goal.

Answer 27

Awnser would be 24!

Answer 28

Hmm not what I got. Make sure you're getting for y as the question asks. And be careful with the signs. Give it one more try and I'll help you after that.

Answer 29

wait im confused cause i got -14 and 24 but those arent right

Answer 30

You have the sign wrong for one of them. Here
Solve the following system:
{3 x-6 y = 12 | (equation 1)
3 y-2 x = 6 | (equation 2)
Add 2/3 × (equation 1) to equation 2:
{3 x-6 y = 12 | (equation 1)
0 x-y = 14 | (equation 2)
Divide equation 1 by 3:
{x-2 y = 4 | (equation 1)
0 x-y = 14 | (equation 2)
Multiply equation 2 by -1:
{x-2 y = 4 | (equation 1)
0 x+y = -14 | (equation 2)
Add 2 × (equation 2) to equation 1:
{x+0 y = -24 | (equation 1)
0 x+y = -14 | (equation 2)
Collect results:
Answer: |
| {x = -24
y = -14

Answer 31

oh i did it backwards got y for 24 and x as -14

Answer 32

Do you get how Wolfe solved it?

Answer 33

yep he went step by step that made me understand it :)

Answer 34

WAIT

Answer 35

huh?

Answer 36

Oh ok nvm I thought I had the equations wrong

Answer 37

Sorry haven't got the chance to help. I did something. hehe ^_^ Good job!

Answer 38

can u help me with two more please!!!!!!!!

Answer 39

@wolfe know how to explain so i can understand other pl just give out the awnser

Answer 40

Sure make a new post but I'll eat first.

Answer 41

@wolfe8 is a great helper ^_^ hehe
