A linear programming problem can be both unbounded and infeasible.

Decision variables limit the degree to which the objective in a linear programming problem is satisfied.

Which of the following statements is NOT true?

Muir Manufacturing produces two popular grades of commercial carpeting among its many other products. In the coming production period, Muir needs to decide how many rolls of each grade should be produced in order to maximize profit. Each roll of Grade X carpet uses 50 units of synthetic fiber, requires 25 hours of production time, and needs 20 units of foam backing. Each roll of Grade Y carpet uses 40 units of synthetic fiber, requires 28 hours of production time, and needs 15 units of foam backing. The profit per roll of Grade X carpet is $200 and the profit per roll of Grade Y carpet is $160. In the coming production period, Muir has 3000 units of synthetic fiber available for use. Workers have been scheduled to provide at least 1800 hours of production time (overtime is a possibility). The company has 1500 units of foam backing available for use. Develop and solve a linear programming model for this problem.

Does the following linear programming problem exhibit infeasibility, unboundedness, or alternate optimal solutions? Explain.

In a linear programming problem, the objective function and the constraints must be linear functions of the decision variables.

Alternative optimal solutions occur when there is no feasible solution to the problem.

Solve the following linear program by the graphical method.

An infeasible problem is one in which the objective function can be increased to infinity.

For the following linear programming problem, determine the optimal solution by the graphical solution method

The maximization or minimization of a quantity is the

As long as the slope of the objective function stays between the slopes of the binding constraints

It is possible to have exactly two optimal solutions to a linear programming problem.

A redundant constraint is a binding constraint.

Find the complete optimal solution to this linear programming problem.

No matter what value it has, each objective function line is parallel to every other objective function line in a problem.

Which of the following is a valid objective function for a linear programming problem?

Only binding constraints form the shape (boundaries) of the feasible region.
