MAAP Algebra I 2 — Questions and Answers
Question 1: Which inequality represents the phrase 'x is at most 15'?
- x > 15
- x < 15
- x ≥ 15
- x ≤ 15 (Correct answer)
Correct answer: x ≤ 15
'At most 15' means x can equal 15 or be less, written as x ≤ 15.
Question 2: What is the solution to -3x > 12?
- x > -4
- x < -4 (Correct answer)
- x > 4
- x < 4
Correct answer: x < -4
Dividing both sides by -3 and flipping the inequality sign gives x < -4.
Question 3: Which is the correct simplification of 5x + 3y - 2x + y?
- 3x + 4y (Correct answer)
- 7x + 4y
- 3x + 2y
- 7x + 2y
Correct answer: 3x + 4y
Combining like terms: (5x - 2x) + (3y + y) = 3x + 4y.
Question 4: If f(x) = 4x - 1, what is f(3)?
- 7
- 10
- 11 (Correct answer)
- 12
Correct answer: 11
f(3) = 4(3) - 1 = 12 - 1 = 11.
Question 5: Which table of values represents a proportional relationship?
- x: 1,2,3 | y: 3,5,7
- x: 1,2,3 | y: 2,4,6 (Correct answer)
- x: 1,2,3 | y: 1,3,6
- x: 1,2,3 | y: 4,6,9
Correct answer: x: 1,2,3 | y: 2,4,6
In a proportional relationship, y/x is constant; for x: 1,2,3 and y: 2,4,6, the ratio y/x = 2 for all pairs.
Question 6: What is the degree of the polynomial 3x⁴ - 2x² + x - 5?
- 1
- 2
- 4 (Correct answer)
- 5
Correct answer: 4
The degree of a polynomial is the highest exponent of the variable, which is 4 here.
