Monitoring Progress and Modeling with Mathematics In Exercises 3-6, write a compound inequality that is represented by the graph. 12. MODELING WITH MATHEMATICS The life zones on Mount Rainier, a mountain in Washington, can be 3. approximately classified by elevation, as follows. Low-elevation forest: above 1700 feet to 2500 feet 4. 4 1+ Mid-elevation forest: above 2500 feet to 4000 feet Subalpine: above 4000 feet to 6500 feet Alpine: above 6500 feet to the summit 5. -10 In Exercises 7-10, write the sentence as an inequality. Graph the inequality. (See Example I.) Elevation of Mount Rainier: 14,410 ft 7. A number p is less than 6 and greater than 2. Write a compound inequality that represents the elevation range for each type of plant life. 8. A number n is less than or equal to -7 or greater than 12. a. trees in the low-elevation forest zone b. flowers in the subalpine and alpine zones 9. A number m is more than -7, or at most - 10. In Exercises 13-20, solve the inequality. Graph the 10. A number r is no less than -1.5 and fewer than 9.5. solution. (See Examples 2 and 3.) 13. 6 -3r2 -9 11.
