An objective function and a system of linear inequalities representing constraints are given.
a. Graph the system of inequalities representing the constraints.
b. Find the value of the objective function at each corner of the graphed region.
c. Use the values in part (b) to determine the maximum value of the objective function and the values of x and y for which the maximum occurs.
\(\displaystyle{z}={2}{x}+{3}{y}\)
\(\displaystyle{\left\lbrace\begin{array}{c} {x}{\quad\text{and}\quad}{y}\ge{0}\\{2}{x}+{y}\le{8}\\{2}{x}+{3}{y}\le{12}\end{array}\right.}\)

Sketch the region that corresponds to the given inequalities, say whether the region is bounded or unbounded, and find the coordinates of all corner points (if any).
\(\displaystyle{x}+{y}\ge{5}{\left({1}\right)}\)
\(\displaystyle{x}\le{10}{\left({2}\right)}\)
\(\displaystyle{y}\le{5}{\left({3}\right)}\)
\(\displaystyle{x},{y}\ge{0}{\left({4}\right)}\)

Answer 1

Step 1
For the inequalities we make auxiliary equations.
x=0 ,x+y=4, 2x+y=5
x>=0
\(\displaystyle{x}+{y}\le{4}\)
\(\displaystyle{2}{x}+{y}\le{5}\)
x=0
x+y=4
2x+y=5
Step 2
Then we make table for the equations and graph:

Step 4
Then shade the regions according to the inequalities.
For \(\displaystyle{x}\ge{0}\), shade the right side of x=0
For \(\displaystyle{x}+{y}\le{4}\), shadetowards (0,0) because x=0, y=0 satisfies the inequality.
For \(\displaystyle{2}{x}+{y}\le{5}\), shade towards (0,0) because x=0, y=0 satisfies the inequality.
So the common region is the shaded region in black.
