If computers sell for $1290 per unit and hard drives sell for $125 per unit, the revenue from x computers and y hard drives can be represented by

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

what do u need to know

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
