c.-4x^2-2x+1
d. -2x^2-4x+1

answer: i oofed

step-by-step explanation:

oofed=wow

idk bring the function back   im not smart

step-by-step explanation:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
