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
