What is the domain of f(x)? {x| –4 < x ≤ 4} {x| –3 < x ≤ 4} {x| 1 < x ≤ 4} {x| 2 < x ≤ 4}

do i do it on a graph?

step-by-step explanation:

29933333.33

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

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
