To calculate: The coordinates of the vertices of the feasible region formed by graphing the given inequalities

Answer to Problem 15PPS
The graph of the given system of inequalities is,
The coordinates of the feasible region are
The maximum value of the function is
Explanation of Solution
Given information:
The inequalities
Formula used:
Linear programming is a technique to find the maximum and the minimum value of a given function over a given system of some inequalities, with each inequality representing a constraint. Graph the inequalities and obtain the vertices of the feasible region (solution set). Substitute the coordinates of the feasible region in the function and determine the maximum and the minimum value.
Calculation:
Consider the provided system of inequalities
Recall that linear programming is a technique to find the maximum and the minimum value of a given function over a given system of some inequalities, with each inequality representing a constraint. Graph the inequalities and obtain the vertices of the feasible region (solution set).
Graph the given inequalities as,
In the above graph, red region represents the inequality
The feasible region is the region common to all the inequalities which is represented as,
The coordinates of the vertices of the feasible region are
Now, to find the maximum and minimum value of the function, substitute the coordinates of the feasible region in the function and determine the maximum and the minimum value.
So, substitute
From the above table, it is observed that the maximum value of the function is
Thus, graph of the given system of inequalities is,
The coordinates of the feasible region are
