Graph each system of inequalities.
Answer to Problem 90RE
Explanation of Solution
Given information:
Graph each system of inequalities.
Calculation:
Consider the sytem of inequalities.
Let take inequality,
To determine the part of the graph to be shaded use a test point
Substitute
Since
Hence the complete solution is set all the points which are opposite side of the curve as the point
Now consider,
Substitute
Since
Hence the complete solution is set all the points which are on the same side of the line as the point
So the solutions of all inequalities are satisfying and the graph is sketched in the rectangular Cartesian coordinate system as given below.
Hence, the graph of inequalities is as shown.
