Front

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

Back

It represents all numbers to the left of -4, not including -4 itself.

Front

How do you write an inequality for Cameron's bowling scenario?

Back

8x + 6 ≤ 42, where x is the number of games.

Front

What is the total cost equation for Katie's taxi ride?

Back

1.75 + 0.65m < 10, where m is the number of miles.

Front

What does the inequality -6x - 4 > -40 mean?

Back

It means that the expression -6x - 4 is greater than -40.

Front

How do you solve the inequality -8k - 4 ≤ -60?

Back

Add 4 to both sides to get -8k ≤ -56, then divide by -8 to find k ≥ 7.

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 graph the inequality x < 4?

Back

Draw a number line, shade to the left of 4, and use an open circle at 4.

Front

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

Back

Subtract 5 from both sides to isolate the term with x.
