Question

1. 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

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

Step2: Simplify both sides

$x \leq -4$

Answer:

b. $x \leq -4$
