You have been studying linear and nonlinear functions. Among the nonlinear functions are quadratic functions. A quadratic function has a squared
variable (x) in its equation. The graph of a quadratic function is a U-shaped
curve called a parabola.

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
