Answer:

A

Step-by-step explanation:

Given

12x + 7 < - 11 or 5x - 8 > 40

Solve each inequality

12x + 7 < - 11 ( subtract 7 from both sides )

12x < - 18 ( divide both sides by 12 )

x < - [tex]\frac{3}{2}[/tex]

OR

5x - 8 > 40 ( add 8 to both sides )

5x > 48 ( divide both sides by 5 )

x > [tex]\frac{48}{5}[/tex]

Solution is

x < - [tex]\frac{3}{2}[/tex] or x > [tex]\frac{48}{5}[/tex] → A
