Front

Definition of a solution set in algebra.

Back

A solution set is the set of all values that satisfy a given equation or inequality.

Front

What is the process to solve a linear equation?

Back

1. Isolate the variable on one side of the equation. 2. Simplify both sides if necessary. 3. Solve for the variable.

Front

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

Back

A point is a solution if it satisfies all equations in the system.

Front

How do you estimate square roots?

Back

Find two perfect squares between which the number lies and determine which is closer.

Front

What is the difference between an open interval and a closed interval?

Back

An open interval does not include its endpoints, while a closed interval includes its endpoints.
