Front

What does the solution to a system of equations represent?

Back

The point(s) where the equations intersect on a graph.

Front

Define an inequality.

Back

A mathematical statement that compares two expressions using symbols like <, >, ≤, or ≥.

Front

What is the difference between x > 5 and x ≥ 5?

Back

x > 5 means x is greater than 5; x ≥ 5 means x is greater than or equal to 5.

Front

How do you graph the inequality x < 4?

Back

Draw a number line, place an open circle at 4, and shade to the left.

Front

What does the shaded region in a graph of inequalities represent?

Back

The set of all possible solutions that satisfy the inequalities.
