Systems of Linear Inequalities: Systems Of Linear Inequalities Worksheet With Answers

Systems of linear inequalities are a set of two or more linear inequalities that are combined together to define a region of points in a graph. Linear inequalities are equations that represent a straight line on a graph, and they can be used to define the boundaries of a region.

Systems of linear inequalities can be used to solve a variety of problems, such as finding the feasible region for a system of constraints or finding the optimal solution to a linear programming problem.

Graphing Systems of Linear Inequalities

To graph a system of linear inequalities, first graph each individual inequality on the same coordinate plane. The solution region is the region that satisfies all of the inequalities. For example, the system of inequalities

“`y > 2x + 1y < -x + 3 ```

would be graphed as follows:

[Image of a graph of the system of inequalities y > 2x + 1 and y< -x + 3]

The solution region is the shaded region in the graph.

Solving Systems of Linear Inequalities, Systems of linear inequalities worksheet with answers

There are several methods for solving systems of linear inequalities. One method is to use substitution. To use substitution, solve one of the inequalities for one of the variables and then substitute that expression into the other inequality. For example, to solve the system of inequalities

“`y > 2x + 1y < -x + 3 ```

you could solve the first inequality for y:

“`y > 2x + 1y = 2x + 2“`

Then you could substitute this expression for y into the second inequality:

“`y < -x + 3 2x + 2 < -x + 3 ```

You could then solve this inequality for x:

“`2x + 2 < -x + 3 3x < 1 x < 1/3 ```

Therefore, the solution to the system of inequalities is x < 1/3 and y >2x + 1.

Applications of Systems of Linear Inequalities

Systems of linear inequalities have a variety of applications in the real world. For example, they can be used to:

• Find the feasible region for a system of constraints. For example, a company might have a set of constraints on the production of two products. The company could use a system of linear inequalities to find the feasible region, which is the set of all possible production levels that satisfy the constraints.

• Find the optimal solution to a linear programming problem. For example, a company might want to find the optimal production levels for two products that maximize profit. The company could use a system of linear inequalities to find the optimal solution.
