Module 6 Review (systems)

Front

What is a system of equations?

Back

A set of two or more equations with the same variables that are solved together.

Front

What is the elimination method in solving systems of equations?

Back

A method that involves adding or subtracting equations to eliminate one variable, making it easier to solve for the other.

Front

Solve the system of equations using the elimination method: -9x - 4y = -20 and 5x + 4y = 4.

Back

(4, -4)

Front

What does it mean for a solution to a system of equations to be consistent?

Back

A consistent system has at least one solution.

Front

What does it mean for a solution to a system of equations to be inconsistent?

Back

An inconsistent system has no solutions.

Front

What is a system of inequalities?

Back

A set of two or more inequalities with the same variables that are solved together.

Front

How do you graph a system of inequalities?

Back

Graph each inequality on the same coordinate plane and identify the region that satisfies all inequalities.

Front

Which inequalities match the graph: y > 2x - 4 and y < 2?

Back

y > 2x - 4 and y < 2.

Front

What is the solution to the system of equations shown in the graph?

Back

(2, 2)

Front

What does it mean for a solution set to be bounded?

Back

A bounded solution set is enclosed within a certain area on the graph.
