Solve the system using elimination. 3x – 4y = 9 –3x + 2y = 9

X=9

Y=-9

Step-by-step explanation:

3x - 4y =9

-3x +2y=9 cross 3x and - 3x since they're opposite ــــــــــــــــــــــــ

-4y +2y =9 +9

-2y =18

Y =-18/2

Y= -9

Replace y in the first equation:

3x - 4 (-9)=9

3x +36=9

3x = 27

X= 27/3

X= 9

Hope this helps you.. Good luck

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
