What is a system of inequalities?

Back

A system of inequalities is a set of two or more inequalities that share the same variables. The solution is the set of all points that satisfy all inequalities in the system.

How do you represent a word problem as a system of inequalities?

Back

Identify the variables, determine the constraints, and translate the conditions into inequalities.

What does the inequality x + y < 10 represent in a word problem?

Back

It indicates that the total number of items represented by x and y must be less than 10.

What does the inequality 2x + 3y ≥ 20 represent in a word problem?

Back

It indicates that the total points scored from x two-point shots and y three-point shots must be at least 20.

What is the significance of the '≥' symbol in inequalities?

Back

The '≥' symbol means 'greater than or equal to', indicating that the value can be either greater than or exactly equal to the number.

Front

What is the significance of the '<' symbol in inequalities?

Back

The '<' symbol means 'less than', indicating that the value must be strictly less than the number.

How do you graph a system of inequalities?

Back

Graph each inequality on the same coordinate plane, shading the region that satisfies all inequalities.

Front

What does it mean if a point is in the solution region of a system of inequalities?

Back

It means that the point satisfies all inequalities in the system.

What is a feasible region in the context of inequalities?

Back

The feasible region is the area on a graph where all the inequalities in a system are satisfied.

How can you determine if a point is a solution to a system of inequalities?

Back

Substitute the point's coordinates into each inequality. If it satisfies all inequalities, it is a solution.
