3-111.

Solve each inequality and graph the solution on a number line. Homework Help ✎

See the homework help for part (b) of problem 3-103.

Change the inequality to an absolute value equation and solve it to determine the boundary points.

Use the boundary points to create regions on a number line and then test each region to determine if the region is “true” or “false.”

Refer to the Math Notes box in Lesson 3.2.2 for additional help.
