Which is the factored form of x² + 5x + 6?
Answer: (x + 2)(x + 3)
2 and 3 multiply to 6 and add to 5, so the answer is (x + 2)(x + 3).
What is the mean of the data set 3, 7, 8, 10, 17?
Answer: 9
The sum is 45, and 45 ÷ 5 = 9.
If f(x) = 2x² − 3, what is f(−2)?
Answer: 5
(−2)² = 4, so f(−2) = 2(4) − 3 = 5.
Which equation represents a line with slope −3 and y-intercept 4?
Answer: y = −3x + 4
Slope-intercept form is y = mx + b, so m = −3 and b = 4 give y = −3x + 4.
Solve the inequality −2x > 8.
Answer: x < −4
Dividing both sides by −2 reverses the inequality sign, giving x < −4.
A bag has 3 red, 5 blue, and 2 green marbles. What is the probability of randomly picking a blue marble?
Answer: 1/2
There are 5 blue marbles out of 10 total, so the probability is 5/10 = 1/2.
A town's population is 500 and doubles every 3 years. What will the population be after 9 years?
Answer: 4,000
9 years is 3 doublings, so 500 × 2³ = 4,000.
