Review: Writing, Graphing, & Solving One-Step Inequalities

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions using inequality symbols such as <, >, ≤, or ≥.

Front

What does the symbol '≥' mean?

Back

The symbol '≥' means 'greater than or equal to'.

Front

What does the symbol '≤' mean?

Back

The symbol '≤' means 'less than or equal to'.

Front

How do you represent the inequality r ≥ -6 on a number line?

Back

You place a closed dot on -6 and shade to the right.

Front

What does an open dot represent when graphing inequalities?

Back

An open dot represents that the number is not included in the solution (used for < or >).

Front

What does a closed dot represent when graphing inequalities?

Back

A closed dot represents that the number is included in the solution (used for ≤ or ≥).

Front

What happens to the inequality symbol when you multiply or divide by a negative number?

Back

The inequality symbol must be switched (e.g., from < to >).

Front

Solve the inequality: -4p < 36. What is p?

Back

p > -9.

Front

What is the solution to the inequality x ≥ -5?

Back

The solution includes all numbers greater than or equal to -5.

Front

How do you graph the inequality x > 5?

Back

You place an open dot on 5 and shade to the right.
