In this lesson we are going to wrap things up with inequalities by looking at systems of inequalities. We will look at how you can satisfy a system of inequalities rather just individual inequalities. That will bring us to looking at overlapping solution regions. To graph a system of inequalities, graph each inequality separately. The solution region of the system is where the individual graphs overlap. You may use a test point from the overlapping region in the original system to see if the solution region is correct. Look for word problems that involve a range of possibilities to determine if an inequality would be more appropriate when setting it up.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
