What is meant by a system of inequalities?
A system of inequalities is a set of inequalities that you deal with all at once.
Solving a system of inequalities means graphing each individual inequality and then finding the overlaps of the various solutions.
Solve the following system:
Step 1: Solve as many of the inequalities as possible for
Step 2. Graph each inequality, shading the area that satisfies the condition.
This is a ">" inequality, so you use a dashed line to show that
(d) Shade the area that satisfies all the inequalities.
And you have solved your system of inequalities.
