Inequalities - Flip or Nah

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 happens when you multiply or divide both sides of an inequality by a negative number?

Back

You must flip the inequality sign.

Front

Solve the inequality: -4 ≤ -4m. What do you do?

Back

You FLIP the inequality sign when dividing by -4.

Front

Solve the inequality: ¼m < -8. What do you do?

Back

You do NOT flip the inequality sign because you are multiplying by a positive number.

Front

Solve the inequality: 5x < -25. What do you do?

Back

You do NOT flip the inequality sign because you are dividing by a positive number.

Front

What is the result of dividing both sides of an inequality by a negative number?

Back

The inequality sign flips.

Front

Solve the inequality: -5x + 12 > 35. What do you do?

Back

You FLIP the inequality sign when isolating x.

Front

What is the solution to the inequality: 3x - 7 < 2?

Back

Add 7 to both sides, then divide by 3. The solution is x < 3.
