Isolate absolute value expression: First, we need to isolate the absolute value expression on one side of the inequality.∣s∣+2≥18Subtract 2 from both sides to isolate ∣s∣.∣s∣+2−2≥18−2∣s∣≥16
Set up two inequalities: Now that we have ∣s∣ on its own, we can set up two separate inequalities to solve for s because the absolute value of s can be either positive or negative.The two inequalities are:s≥16 and −s≥16
Solve second inequality: To solve the second inequality, −s≥16, we need to multiply both sides by −1. Remember that when we multiply or divide an inequality by a negative number, we must reverse the inequality sign.−s≥16(−1)(−s)≤(−1)(16)s≤−16
Final compound inequality: Now we have two inequalities that represent the solution to the original problem:s≥16 or s≤−16This is the compound inequality that represents all the possible values of s that satisfy the original inequality.
