Q:
# Solve the equation. 3|3k| = 27A.) {-9, 9}B.) {-3, 3)C.) {-3, 9}D.) -3 < k < 3

Accepted Solution

A:

The answer is B. -3, 3

This is why:

3|3*3| = 27

3|9| = 27

3*9 = 27

The same will happen with -3 since this | means the distance from the number to zero and in this case it is 3 units til you reach zero. So the answer is B. 3, -3
