Chapter 11: Q. 9 (page 790)

Solve each linear programming problem.
Maximize $z = 2 x + y$ subject to $\{\begin{cases} x \geq 0 \\ y \geq 0 \\ x + y \leq 6 \\ x + y \geq 1 \end{cases}$

Short Answer

Expert verified

Maximum value is $12$ , we get this value at $(6, 0)$

Step by step solution

Step 1. Given information

The given system of linear inequalities is :

$\{\begin{cases} x \geq 0 \\ y \geq 0 \\ x + y \leq 6 \\ x + y \geq 1 \end{cases}$

The goal of the task is to solve the problem of linear programming. We are looking for the largest value that can occur if x and y are solutions of the system. We draw a graph of the system and read the corner points from the graph.

Step 2. Draw the graph of the system

Step 3. Make a table for the corner points

Corner point (x,y)	$z = 2 x + y$
$(0, 1)$	role="math" localid="1646997454100" $z = 1$
$(0, 6)$	$z = 6$
$(6, 0)$	$z = 12$
$(1, 0)$	$z = 2$
