Plug in the solutions into the function y = x + 8
(-2 , 6)
So
y = x + 8
6 = -2 + 8
6 = 6 True
(4 , 12)
y = x + 8
12 = 4 + 8
12 = 12 True
Plug in the solutions into the function 2y = x^2 + 8
(-2 , 6)
2y = x^2 + 8
2(6) = (-2)^2 + 8
12 = 4 + 8
12 = 12 True
(4 , 12)
2y = x^2 + 8
2(12) = (4)^4 + 8
24 = 16 + 8
24 = 24 True
Answer:
A) Both are solutions
