<span>3x + (x-8) = 23
Combine like terms first. You can combine 3x and x because they have the same variable.
4x - 8 = 23

4x = 31
Last step is to divide both sides by 4 to isolate the x.
4/4x = 31/4
x = 7.75 is the answer.</span>

A) the quadratic at y=3.5 is well above the exponential
B) the most likely choice (3.5, 17)
C) at x=-8, the quadratic is above the exponential
D) neither graph goes anywhere near y = -8
