Solving a compound inequality - Free math help

The video tutorial explains how to solve compound inequalities by addressing each inequality separately. It emphasizes the importance of flipping the inequality sign when multiplying or dividing by a negative number. The tutorial also covers graphing these inequalities on a number line, highlighting the significance of closed and open dots to represent inclusive and exclusive values. Finally, it discusses how to interpret the graph to understand the range of solutions for the compound inequality.

How do you determine whether to close or leave the dot open on the graph for the inequality?

Describe the final representation of the inequalities on the number line.
