Answer:

C

Step-by-step explanation:

You can eliminate answer A because when X=1, Y must equal 33.75 not 33.

You can eliminate answer B because when X=0, Y must equal 0 not 1.

You can eliminate answer D because this answer has the X and Y coordinates reversed.  When X=1, Y= 33.75.  When X=4, Y=135, etc.

Solve using elimination 5x+7y=9 <br> 2x-3y=-37
uranmaximum [27]

Answer:

x = -8

y = 7

Step-by-step explanation:

5x + 7y = 9

2x - 3y = -37

1.) First, multiply each side to match either y-values or x-values. (In this example, we'll use match x-values)

10x + 14y = 18 (multiplied by 2)

10x - 15y = -185 (multiplied by 5)

2.) Then, subtract the entirety of one equation to isolate the y-value.

10x + 14y = 18

-10x + 15y = 185

3.) Add and subtract values and divide to find y.

29y = 203

y = 7

4.) Plug-in y to solve for x into one equation, or repeat steps 1-3.

15x + 21y = 27

14x - 21y = -259

29x = -232

x = -8
