Hello!

Answer:


\Large \boxed{\sf A. -7}

Explanation:

We have this inequality:


\sf -5x - 7 \geq 28

Let's solve this inequality:

Add 7 to both sides:


\sf -5x - 7+7 \geq 28+7

Simplify both sides:


\sf -5x \geq 35

Divide both sides by -5, so also change the sign of the inequality


\sf (-5x)/(-5) \leq (35)/(-5)

Simplify both sides:


\boxed{\sf x \leq -7}

So the correct answer is A. -7
