Evaluate an Algebraic Expression Evaluate t – 4 if t = 6. t – 4 = 6 – 4 Replace t with 6. = 2 Subtract. Answer: 2 Interactive Lab: Modeling Algebraic Expressions Example 1

Evaluate 7 + m if m = 4. A. 3 B. 7 C. 11 D. 28 A B C D Example 1

Evaluate 5x + 3y if x = 7 and y = 9.
Evaluate Expressions Evaluate 5x + 3y if x = 7 and y = 9. 5x + 3y = 5(7) + 3(9) Replace x with 7 and y with 9. = Do all multiplications first. = 62 Add 35 and 27. Answer: 62 Example 2

Evaluate 4a – 2b if a = 9 and b = 6.
C. 24 D. 72 A B C D Example 2

Evaluate Expressions Evaluate 5 + a2 if a = 5.
5 + a2 = Replace a with 5. = Evaluate the power. = 30 Add. Answer: 30 Example 3
