Concept explainers
To solve: The inequality and to graph the solution
Answer to Problem 15E
Thesolved inequality is
Explanation of Solution
Given:
Calculation:
Add both sides for both inequalities by
Divide both sides by
Write a compound inequality
Subtract both sides of both inequalities by
Simplify
Since the inequalities are joined by “and”, take the intersection of the inequalities as its solution set.
Therefore, its graph should have a closed point at
Conclusion:
Hence, the solved inequality is
