Front

What is an inequality?

Back

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

Front

What does the symbol ≤ mean?

Back

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

Front

What does the symbol ≥ mean?

Back

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

Front

What is the solution to the inequality 12 - m ≤ 7?

Back

m ≥ 5.

Front

How do you solve the inequality 6t + 4 ≤ -2?

Back

Subtract 4 from both sides to get 6t ≤ -6, then divide by 6 to find t ≤ -1.

Front

What is the solution to the inequality 2k - 9 ≤ -19?

Back

k ≤ -5.

Front

What does it mean to graph an inequality?

Back

Graphing an inequality means representing the solutions of the inequality on a number line.

Front

When graphing the inequality h ≥ 48, what type of dot is used?

Back

A closed dot is used because 48 is included in the solution.

Front

What type of dot is used when graphing h < 48?

Back

An open dot is used because 48 is not included in the solution.

Front

What is the first step in solving the inequality 3x + 5 > 11?

Back

Subtract 5 from both sides to get 3x > 6.
