Back

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

Front

What does the symbol '<' mean?

Back

The symbol '<' means 'less than'.

Front

What does the symbol '>' mean?

Back

The symbol '>' means 'greater than'.

Front

How do you solve the inequality -4 + y < -8?

Back

Add 4 to both sides: y < -4.

Front

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

Back

The inequality symbol flips (changes direction).

Front

Solve the inequality 2x > 10.

Back

Divide both sides by 2: x > 5.

Front

What is the solution to the inequality 8x < 48?

Back

Divide both sides by 8: x < 6.

Front

How do you check if a value satisfies the inequality x + 9 > 21 when x = 15?

Back

Substitute 15 into the inequality: 15 + 9 > 21 is true.

Front

What is the solution to the inequality (n/3) > -20?

Back

Multiply both sides by 3: n > -60.

Front

What does it mean to 'flip' the inequality symbol?

Back

To 'flip' the inequality symbol means to change it from < to > or from ≤ to ≥ when multiplying or dividing by a negative number.
