Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions and shows that one is greater than, less than, greater than or equal to, or less than or equal to the other.

Front

What does the symbol '≥' mean?

Back

'≥' means 'greater than or equal to'.

Front

How do you solve the inequality r - 14 ≥ 17?

Back

Add 14 to both sides to isolate r: r ≥ 31.

Front

What does the symbol '≤' mean?

Back

'≤' means 'less than or equal to'.

Front

How do you solve the inequality 24 ≤ h + 15?

Back

Subtract 15 from both sides to isolate h: h ≥ 9.

Front

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

Back

The inequality sign flips when you multiply or divide both sides by a negative number.

Front

How do you isolate the variable in the equation x - 62 = 123?

Back

Add 62 to both sides: x = 185.

Front

What is the solution to the inequality x + 9 > 21 when x = 15?

Back

True, because 15 + 9 = 24, which is greater than 21.

Front

What is the first step in solving the inequality -2x ≥ 22?

Back

Divide both sides by -2 and flip the inequality sign: x ≤ -11.

Front

What does it mean for a value to satisfy an inequality?

Back

A value satisfies an inequality if, when substituted into the inequality, the statement is true.
