Question

50 POINTS__ Solve for z and graph the solution.

–7 ≥ z–10 ≥ –14

Plot the endpoints. Select an endpoint to change it from closed to open. Select the middle of a segment, ray, or line to delete it.

Answer 1

-7≥7-10≥-14

Separate the compound inequality into two inequalities

7-10<-7
7-10>-14

Solve the inequality for z

7≤3
7-10>-14

Z<3
7>-4

Solution
Z [-4,3]

Alternative Form

{zI-4≤z≤3}
