Q:
# PLEASE HELP AS SOON AS POSSIBLE!!!!!!!!!!!!!!!!!! |r+3| ≥7 solve the inequality (please show work and steps )

Accepted Solution

A:

|r+3| = (r+3) when r ≥ -3 so for r ≥ -3

r + 3 ≥ 7

r ≥ 4

|r+3| = -(r+3) when r < -3 so for r < -3

-(r + 3) ≥ 7

r + 3 ≤ -7

r ≤ -10

The answer to this question is r ≤ -10, r ≥ 4

r + 3 ≥ 7

r ≥ 4

|r+3| = -(r+3) when r < -3 so for r < -3

-(r + 3) ≥ 7

r + 3 ≤ -7

r ≤ -10

The answer to this question is r ≤ -10, r ≥ 4
