Review for Chapter 4b Test Inequalities (Math 7)

Front

What does the inequality x < -4 represent on a number line?

Back

The graph shows all numbers less than -4, extending to the left.

Front

When graphing x ≥ 4, which direction does the graph go?

Back

The graph goes to the right, including 4.

Front

What is the solution to the inequality -6a ≥ -36?

Back

a ≤ 6.

Front

Solve the inequality: x + 5 ≤ 13.

Back

x ≤ 8.

Front

Do you need to flip the inequality sign when solving -3x ≥ 12?

Back

Yes, you flip the sign when dividing by a negative number.

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions using symbols like <, >, ≤, or ≥.

Front

What does the symbol '≤' mean?

Back

It means 'less than or equal to'.

Front

What does the symbol '≥' mean?

Back

It means 'greater than or equal to'.

Front

How do you solve the inequality 2x + 3 < 11?

Back

Subtract 3 from both sides to get 2x < 8, then divide by 2 to find x < 4.

Front

What is the first step in solving the inequality 5x - 2 ≥ 3?

Back

Add 2 to both sides to get 5x ≥ 5.
