Let v= (5,-2) and w=(4,10). which of the following is true? check all that apply a. w=-2(-2,-5) b. v and w are perpendicular c. v+w=20 d. the y component of w is 10

All of them except B (apex) verified

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
