Which equation represents a linear function? O A. y = 2x + 7
O B. y = x2 + 4
O C. y = x(x + 1)
OD. y = 2x3

A

Step-by-step explanation:

y= 2X +7

y=2(3)+7

y=6+7

y=13

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

multiple all that
