3.2 Review Worksheet, Part 2
3.2.3 Solving Compound Inequalities 1. Earth’s atmosphere is made of several layers. A layer called the stratosphere extends from about 16 km above Earth’s surface to about 50 km above Earth’s surface. Write a compound inequality to show the altitudes that are within the range of the stratosphere. Graph the solutions.
Solve each compound inequality and graph the solutions. 2. − 1 < x + 1 < 1
3. 1 ≤ 2 n − 5 ≤ 7
4. − 2 < x − 2 < 2
5. 5 < 3 x − 1 < 17
6. x − 4 < − 7 OR x + 3 > 4
7. 2 x + 1 < l OR x + 5 > 8
8. x + 1 < 2 OR x + 5 > 8
9. x + 3 < 0 OR x − 2 > 0
Write the compound inequality shown by each graph. 10. 11. –3–2–101234567
