“x is greater than or equal to -4 and less than or equal to 2” Solving Compound Inequalities Containing “AND” Solutions of Compound Inequalities joined by “AND”: It is read: The graph shows that the OVERLAP of the solutions is the solution to the compound inequality! Write the compound inequality that represents each situation. Then graph it to show the solutions. 1. 2. 3. All real numbers that 4. All real numbers that are are between -10 and 10. at least 40 and at most 60. 5. Today’s temperature will be 6. The books were priced between above 32°F, but not as high as 40°F. $3.50 and $6.00, inclusive. Any number that makes BOTH inequalities true “x is greater than or equal to -4 and less than or equal to 2” OR “x is between -4 and 2, inclusive”

You can solve compound inequalities involving “AND” two different ways: Solve each inequality and graph your solutions. 7. 8. 9. You can separate the inequality into two pieces. (HINT: the middle expression is found in both pieces) Solve each separately. Draw graphs of each. The solution is the overlap! Isolate the variable between the two inequality signs. *Instead of just doing the “same thing to both sides,” you must do the same thing to ALL THREE “SIDES” Separate into two inequalities. Draw graphs of each. The solution is the overlap!
