6) 9x - 7y = -4
18x - 14 y = 10
A) (8, -1)
C) (-8,-8)
B) (-8,-1)
D) No solution

D). No solution

Step-by-step explanation:

9x - 7y = -4

18x - 14 y = 10

9x - 7y = 5

9x - 7y = -4

9x - 7y = 5

--

0 = -9

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
