Answer to Problem 6CFU
Explanation of Solution
Given information:
Calculation:
This inequality has two parts as shown below.
Rearrange the both the inequality as follows:
For inequality (1), dotted line is used to graph a line because the inequality has
For inequality (2), solid line is used to graph a line because the inequality has
