For this case we have to find the average rate of change of a parabola in the interval from to . To do this, we need two points for the parabola pass, and apply the following formula:

We have the following points, taking into account that:

Substituting:

So, the average rate of change for the given graph is 0 in the given interval

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
