Answer 1

Have you attempted to solve this yet?

Answer 2

Not really.

Answer 5

The options are -4, 1)
(2, -1)
(4, -1)
(5, -2)

Answer 6

Lol cmon jason

Answer 7

Lol, Sorry man. I hate this stuff.

Answer 8

I have 2 more. xD

Answer 9

y= x-1/3
y= 3 +1x

Answer 10

wait what

Answer 11

2(5) + 2(-2) =
10 + (- 4) = 6

D

Answer 12

why are u giving coordinates

Answer 13

Thanks SuperFly!!!! I have 2 more if your not busy. Its okay if you dont want to.

Answer 14

Solve the following system of equations:

x - 2y = 14
x + 3y = 9

(1, 12)
(-1, -12)
(12, -1)
(12, 1)

Answer 15

Ok, just gimme the options too

Answer 16

Anyone up for it?

Answer 17

And Solve the system of equations by substitution. What is the solution for x?

2x + y = 1
4x + 2y = -1

x = 0
x = 2
There is no x value, as there is no solution.
x can be any value, as there is an infinite number of solutions.

Answer 18

12 -(-2) =
12 + 2 = 14

C for the first one

Answer 19

Is that for the second one?

Answer 20

Oh Okay the first one

Answer 21

Yeah second one

Answer 22

Okay

Answer 23

Substitution:
x + 3y = -1 So then by subtracting 3y... x = -1 - 3y
The other equation is 2x + 2y = 6
Substitute
2(-1 - 3y) + 2y = 6
-2 -6y + 2y = 6
-2 -4y =6
-4y = 8
y = 2
Substitute again
x + 3(2) = -1
x + 6 = -1
x = - 7
and because (x,y)
(-7,2)

Answer 24

^ thanks!!!!

Answer 25

And what about the final one?

Answer 26

And Solve the system of equations by substitution. What is the solution for x?

2x + y = 1
4x + 2y = -1

x = 0
x = 2
There is no x value, as there is no solution.
x can be any value, as there is an infinite number of solutions.

Answer 27

Do the same thing, first isolate y in 2x + y = 1, what would that look like?

Answer 28

y=2x +1?

Answer 29

I thinks its C
