MPT Technical Foundations 2 — Questions and Answers
Question 1: What is the value of |−15| + |−3|?
- 12
- 18 (Correct answer)
- −18
- −12
Correct answer: 18
Absolute value makes both terms positive: 15 + 3 = 18.
Question 2: Simplify: (3x²)(4x³)
- 7x⁵
- 12x⁵ (Correct answer)
- 12x⁶
- 7x⁶
Correct answer: 12x⁵
Multiply coefficients (3·4=12) and add exponents (2+3=5) to get 12x⁵.
Question 3: What is 15% of 240?
- 32
- 36 (Correct answer)
- 40
- 48
Correct answer: 36
0.15 × 240 = 36.
Question 4: Which of the following is equivalent to 2⁻³?
- −8
- −6
- 1/6
- 1/8 (Correct answer)
Correct answer: 1/8
A negative exponent means take the reciprocal: 2⁻³ = 1/2³ = 1/8.
Question 5: If 5x − 7 = 3x + 9, what is x?
Correct answer: 8
Subtract 3x and add 7 to both sides: 2x = 16, so x = 8.
Question 6: What is the slope of the line passing through (2, 5) and (6, 13)?
Correct answer: 2
Slope = (13−5)/(6−2) = 8/4 = 2.
Question 7: Evaluate: 4! ÷ 2!
Correct answer: 12
4! = 24 and 2! = 2, so 24 ÷ 2 = 12.
