One and two step inequalities

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

How do you represent a maximum speed limit in an inequality?

Back

You represent a maximum speed limit as 's ≤ speed limit'.

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

Write an inequality for: 'A number n is at least 10.'

Back

n ≥ 10.

Front

Write an inequality for: 'A number x is less than 5.'

Back

x < 5.

Front

How do you solve the inequality: 3x + 5 < 20?

Back

Subtract 5 from both sides: 3x < 15, then divide by 3: x < 5.

Front

What is the solution to the inequality: 2n - 4 ≥ 10?

Back

Add 4 to both sides: 2n ≥ 14, then divide by 2: n ≥ 7.

Front

How do you graph the inequality x > 3?

Back

Draw an open circle on 3 and shade to the right.
