Week 12 Day 1 - One-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 solve the inequality k/-12 ≤ -7?

Back

Multiply both sides by -12, remembering to flip the inequality sign: k ≥ 84.

Front

What is the solution to the inequality 3x ≥ 12?

Back

x ≥ 4.

Front

When do you flip the inequality sign?

Back

You flip the inequality sign when you multiply or divide both sides by a negative number.

Front

What does the inequality x ≥ 15 represent in a real-world context?

Back

It represents that a student must be at least 15 years old to obtain a driver's permit.

Front

What does the graph of x ≥ -5 look like?

Back

It includes all numbers greater than or equal to -5, represented by a solid dot at -5 and a line extending to the right.

Front

What is the solution to the inequality k < 10?

Back

k can be any number less than 10.

Front

What is the difference between '>' and '≥'?

Back

'>' means greater than, while '≥' means greater than or equal to.
