Answer:

f(u) = 9/5

Step-by-step explanation:

u - 5 = -4(u - 1) Distribute on the right side

u - 5 = -4u + 4

+4u +4u Add 4u to both sides

5u - 5 = 4

+ 5 + 5 Add 5 to both sides

5u = 9 Divide both sides by 5

u = 9/5

If the endpoints of AB have the coordinates A(9, 8) and B(-1, -2), what is the midpoint of AB?

pickupchik [31]

The midpoint, if the endpoints are (x₁,y₁) and (x₂,y₂):
$(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$

$(9,8) \\
x_1=9 \\ y_1=8 \\ \\
(-1,-2) \\
x_2=-1 \\ y_2=-2 \\ \\
\frac{x_1+x_2}{2}=\frac{9-1}{2}=\frac{8}{2}=4 \\
\frac{y_1+y_2}{2}=\frac{8-2}{2}=\frac{6}{2}=3$

The midpoint of AB is (4,3).
