Concept

Replace x with 4. Multiply 2 and 4 first. Subtract 8 from 6. Add. Evaluate an Expression with Absolute Value Replace x with 4. Multiply 2 and 4 first. Subtract 8 from 6. Add. Answer: 4.7 Example 1

A. 18.3 B. 1.7 C. –1.7 D. –13.7 Example 1

Case 1 a = b y + 3 = 8 y + 3 – 3 = 8 – 3 y = 5 Case 2 a = –b Solve an Absolute Value Equation Case 1 a = b y + 3 = 8 y + 3 – 3 = 8 – 3 y = 5 Case 2 a = –b y + 3 = –8 y + 3 – 3 = –8 – 3 y = –11 Check |y + 3| = 8 |y + 3| = 8 ? |5 + 3| = 8 ? |–11 + 3| = 8 ? |8| = 8 ? |–8| = 8  8 = 8  8 = 8 Answer: The solutions are 5 and –11. Thus, the solution set is –11, 5. Example 2

What is the solution to |2x + 5| = 15? B. {–10, 5} C. {–5, 10} D. {–5} Example 2

|6 – 4t| + 5 = 0 Original equation No Solution Solve |6 – 4t| + 5 = 0. |6 – 4t| + 5 = 0 Original equation |6 – 4t| = –5 Subtract 5 from each side. This sentence is never true. Answer: The solution set is . Example 3

A. B. C. D. Example 3

One Solution Case 1 a = b 8 + y = 2y – 3 8 = y – 3 11 = y Example 4
