How do you solve the inequality -4 + y < -8?

Back

To solve -4 + y < -8, add 4 to both sides: y < -4.

Front

What is the solution to the inequality 8x < 48?

Back

To solve 8x < 48, divide both sides by 8: x < 6.

Front

How do you check if a value satisfies the inequality x + 9 > 21 when x = 15?

Back

Substitute 15 into the inequality: 15 + 9 > 21 is true.

Front

What is the solution to the inequality x + 5 > 7?

Back

To solve x + 5 > 7, subtract 5 from both sides: x > 2.

Front

How do you solve the inequality -8x < 48?

Back

To solve -8x < 48, divide both sides by -8 (remember to flip the inequality): x > -6.

Front

What does it mean to flip the inequality sign?

Back

Flipping the inequality sign occurs when you multiply or divide both sides of an inequality by a negative number.

Front

What is a one-step inequality?

Back

A one-step inequality is an inequality that can be solved in a single operation, such as addition, subtraction, multiplication, or division.
