Q1. Solve the following inequality. Graph the solution set and write it in interval notation:
Background
Topic: Linear Inequalities
This question tests your ability to solve linear inequalities in one variable, graph the solution on a number line, and express the solution in interval notation. These are foundational skills in intermediate algebra.
Key Terms and Formulas
Inequality: A mathematical statement that compares two expressions using symbols such as , , , or .
Interval Notation: A way to describe the set of solutions to an inequality using parentheses and brackets.
Addition Property of Inequality: You can add (or subtract) the same value from both sides of an inequality without changing its direction.
Step-by-Step Guidance
Start by writing the inequality:
Subtract from both sides to get all terms on one side:
Combine like terms to simplify both sides:
Add $13xx - 13 + 13 < -8 + 13$
Simplify the right side to get by itself. (Pause here before the final calculation!)
