Question

what is the solution to $-4x \geq 16$?
a. $x \geq -4$
b. $x \leq -4$
c. $x \leq 4$
d. $x \geq 4$

Explanation:

Step1: Divide both sides by -4

When dividing by a negative number, reverse the inequality sign: $\frac{-4x}{-4} \leq \frac{16}{-4}$

Step2: Simplify both sides

$x \leq -4$

Answer:

b. $x \leq -4$
