Review (In Class) 1 and 2 Step Inequalities

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions using inequality 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 solve the inequality m - 9 ≤ 20?

Back

Add 9 to both sides to get m ≤ 29.

Front

When graphing inequalities, what does a closed circle indicate?

Back

A closed circle indicates that the number is included in the solution (used for ≤ or ≥).

Front

What does an open circle indicate when graphing inequalities?

Back

An open circle indicates that the number is not included in the solution (used for < or >).

Front

How do you solve the inequality 6b > -24?

Back

Divide both sides by 6 to get b > -4.

Front

What is the solution to the inequality w ≥ 17?

Back

The solutions include all numbers greater than or equal to 17, such as w = 17, w = 18, w = 20.

Front

Which solution is NOT valid for w ≥ 17?

Back

w = 16 is NOT valid because it is less than 17.

Front

What happens to the inequality sign when you divide by a negative number?

Back

The inequality sign flips when you divide or multiply both sides by a negative number.
