Answer:

A

Step-by-step explanation:

Given

5x - 4 ≥ 12 or 12x + 5 ≤ - 4

Solve each inequality

5x - 4 ≥ 12 ( add 4 to both sides )

5x ≥ 16 ( divide both sides by 5 )

x ≥ [tex]\frac{16}{5}[/tex]

OR

12x + 5 ≤ - 4 ( subtract 5 from both sides )

12x ≤ - 9 ( divide both sides by 12 )

x ≤ - [tex]\frac{3}{4}[/tex]

Solution is x ≥ [tex]\frac{16}{5}[/tex] or x ≤ - [tex]\frac{3}{4}[/tex] → A
