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

'≥' means 'greater than or equal to'.

Front

What does the symbol '≤' mean?

Back

'≤' means 'less than or equal to'.

Front

How do you solve the inequality 7k - 2 ≥ -9?

Back

Add 2 to both sides: 7k ≥ -7. Then divide by 7: k ≥ -1.

Front

What is the solution to the inequality 12 ≥ 6w?

Back

Divide both sides by 6: 2 ≥ w or w ≤ 2.

Front

How do you solve the inequality 7n > 49?

Back

Divide both sides by 7: n > 7.

Front

What is the first step in solving the inequality 3x + 5 < 14?

Back

Subtract 5 from both sides: 3x < 9.

Front

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

Back

You must reverse the inequality sign.

Front

What is the solution to the inequality z ≤ 9?

Back

The solution includes all numbers less than or equal to 9.

Front

How do you graph the inequality x > 3 on a number line?

Back

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