MAP Mathematics 5

Question 1

Which is the factored form of x² + 5x + 6?

Accepted Answer

(x + 2)(x + 3)

Answer

2 and 3 multiply to 6 and add to 5, so the answer is (x + 2)(x + 3).

Question 2

What is the mean of the data set 3, 7, 8, 10, 17?

Accepted Answer

9

Answer

The sum is 45, and 45 ÷ 5 = 9.

Question 3

If f(x) = 2x² − 3, what is f(−2)?

Accepted Answer

5

Answer

(−2)² = 4, so f(−2) = 2(4) − 3 = 5.

Question 4

Which equation represents a line with slope −3 and y-intercept 4?

Accepted Answer

y = −3x + 4

Answer

Slope-intercept form is y = mx + b, so m = −3 and b = 4 give y = −3x + 4.

Question 5

Solve the inequality −2x > 8.

Accepted Answer

x < −4

Answer

Dividing both sides by −2 reverses the inequality sign, giving x < −4.
