PARCC Algebra 2

Question 1

Solve for x: 3(x - 4) = 2x + 5.

Accepted Answer

x = 17

Answer

Distribute to get 3x - 12 = 2x + 5, then x = 17.

Question 2

What is the slope of the line passing through (2, 3) and (6, 11)?

Accepted Answer

2

Answer

Slope = (11 - 3)/(6 - 2) = 8/4 = 2.

Question 3

Factor completely: x^2 - 9.

Accepted Answer

(x - 3)(x + 3)

Answer

This is a difference of squares: x^2 - 9 = (x - 3)(x + 3).

Question 4

If f(x) = 2x + 1, what is f(5)?

Accepted Answer

11

Answer

Substitute 5 for x: 2(5) + 1 = 11.

Question 5

Solve the inequality: 2x - 3 > 7.

Accepted Answer

x > 5

Answer

Add 3 to get 2x > 10, then divide by 2 to get x > 5.
