Answer:

- 145

Step-by-step explanation:

Evaluate g(3) then use the value obtained to evaluate f(x), that is

g(3) = - 2(3) + 1 = - 6 + 1 = - 5 , then

f(- 5) = (- 5)³ + 4(- 5) = - 125 - 20 = - 145

Find the midpoint of the segment with the following endpoints.<br> (7, -2) (1, -10)

dem82 [27]

Answer:

Step-by-step explanation:

The formula of a midpoint of the segment AB:

$M_{AB}\left(\dfrac{x_A+x_B}{2};\ \dfrac{y_A+y_B}{2}\right)$

We have A(7, -2) and B(1, -10). Substitute:

$M_{AB}\left(\dfrac{7+1}{2};\ \dfrac{-2+(-10)}{2}\right)\\\\M_{AB}\left(\dfrac{8}{2};\ \dfrac{-12}{2}\right)\\\\M_{AB}(4;\ -6)$
