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'.

How do you solve the inequality z + 3 ≤ 12?

Back

Subtract 3 from both sides: z ≤ 9.

Front

What is the solution to the inequality x - 5 > 10?

Back

Add 5 to both sides: x > 15.

Front

If x + 9 > 21, what is the value of x?

Back

x > 12.

Front

What does it mean if a solution is 'not true' for an inequality?

Back

It means that the value does not satisfy the inequality when substituted.

Front

How do you represent the inequality 'no more than 35 laps'?

Back

p ≤ 35.

Front

What is the solution to the inequality 11 < a?

Back

a > 11.

Front

How do you graph the inequality z ≤ 9?

Back

Draw a number line, shade to the left of 9, and put a closed circle on 9.
