Answer to Problem 13E
Thesolved inequality is
Explanation of Solution
Given:
Calculation:
Divide both sides by
Write a compound inequality
Subtract both sides for both inequalities by
Divide both sides for both inequalities by
Reverse inequality symbol
Since the inequalities are joined by “or”, take the union of the inequalities as its solution set.
Therefore, its graph should have an open point at
Conclusion:
Hence, the solved inequality is
