How do you solve the inequality -5x - 10 < -25?

Back

To solve the inequality, first add 10 to both sides: -5x < -15. Then divide both sides by -5, remembering to flip the inequality sign: x > 3.

What is the solution set for the inequality -5x - 10 < -25?

Back

The solution set is x > 3.

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 solution set?

Back

A solution set is the set of all values that satisfy a given inequality or equation.

Front

What is the difference between an equation and an inequality?

Back

An equation states that two expressions are equal, while an inequality shows that one expression is greater than or less than another.

Front

What is the first step in solving an inequality?

Back

The first step is to isolate the variable on one side of the inequality.

Front

What does 'x < 7' represent?

Back
