What is the solution to the inequality below?

2(x - 4) > x + 8

• x < 10
• x > 16

• x < 20

• x = 20

• x = 0 or x = 6

• x = 2 or x = 3

• x = 2 or x = 4

• x = 4 or x = 1

Which function has the highest y-intercept?

• 
• 

The function is graphed on a set of axes. Which factorization matches the function?

• f(x) = (x + 2) (x - 6)

• f(x) = (x - 2) (x + 6)

• f(x) = -2x + 6

• f(x) = 6x - 2

Using Process of Elimination or Substitution, find the solution to the system of equations below:

2x - y = 2

2x + y = 6

• x = 0, y = 0

• x = -1, y = 1

• x = 2, y = 2

• x = 2, y = 4

Using Process of Elimination or Substitution, find the solution to the system of equations below:

x + 3y = 4

x = 2 - y

• (- 1, - 1)

• (1, 1)

• (2, 3)

• (4, 5)

What is the product of (4x + 8) and (3x + 2)? (Hint: the Crescent Moon :)

• Degree = 1

• Degree = 2

• Degree = 4

• Degree = 5

• x = 0, x = 25
• x = 0, x = - 25

• x = 1, x = 25

• x = 25, x = - 25

• I. and II. only

• II. and III. only

• I. and III. only

• I., ii., and III.
