Answer:

x ≤ 7

Step-by-step explanation:

(2x-4) + 110 ≤ 120

Combine like terms

2x +106 ≤ 120

Subtract 106 from each side

2x+106 -106 ≤ 120-106

2x ≤ 14

Divide each side by 2

2x/2 ≤ 14/2

x ≤ 7

The midpoint of the line having the endpoints $(x_1,y_1)$ and $(x_2,y_2)$ is $(\frac{x_{1}+_x_{2}}{2}, \frac{y_{1}+_y_{2}}{2})$
basically average them

so given that the line has the endpoints of (-3,7) and (9,-2)
x₁=-3
y₁=7
x₂=9
y₂=-2

so the midpoint can be found by doing
$(\frac{-3+9}{2}, \frac{7+(-2)}{2})=$
$(\frac{6}{2}, \frac{7-2}{2})=$
$(3, \frac{5}{2})$

the midpoint is $(3,\frac{5}{2})$
