How do you represent a situation where a variable must be greater than a certain value?

Back

You represent it using the '>' symbol, for example, x > 8 means x must be greater than 8.

What is the solution set of an inequality?

Back

The solution set of an inequality is the set of all values that satisfy the inequality.

How do you solve the inequality -2x + 7 < 19?

Back

To solve -2x + 7 < 19, first subtract 7 from both sides to get -2x < 12, then divide by -2 (remember to flip the inequality sign) to get x > -6.

What is a boundary point in the context of inequalities?

Back

A boundary point is a value that defines the limits of the solution set, often represented by the equality part of the inequality.
