Section 1.7 Solving Compound Inequalities

2
At least $5.20/hr but less than $8.35/hr How would you express: At least 550 and no more than 600 $5.20 ≤ x < $8.35 550 ≤ x ≤ 600 These are called compound inequalities

3
Compound Inequalities can be in 2 forms I.) 25 < x < 50 Read: x is greater than 25 and less than 50 II.) x > 10 or x < 5 Read: x is greater than 10 or less than 5

4
Conjunctions: are compound inequalities joined by the word “and”. Points found in both A and B are the solution set. AB Overlap

5
Disjuntions: are compound inequalities joined by the word “or”. The solution is all Points in either A or B both AB Union

6
1.) Solve: 8 ≤ m + 6 ≤ 14 Overlapping area is the area in between
