Algebra 2: 1st - 3rd Quarter Review

• x = -3

• x = 6

• x = 5

• x = 2

4|5x-2|+7>39

• -6/5<x>2
• x=2 or x=-6/5
• x=2 and x=-6/5
• x<-6/5 or x>2

Solve for x
3 l 4w−1 l −5 = 10

• x = 1.5 and x =-1
• x = -1.5 and x = 1
• x =1 and x = -1
• No Solution

Find the equation of the line that goes through the points (3,8) and (9,16).

• y = 4/3x - 12
• y = 4/3
• y = 4/3x + 4
• 4/3

Write an equation of a line perpendicular to 2x - 7y = 35 through (2, -3)

• y = -7/2x + 4

• y = -4x - 7/2

• y = 4x - 7/2

• y = 7/2x + 4

Solve the system of equations by elimination.
-x + y = -13
-8x - 4y = -8 

• (5, 8)
• (5, -8)
• (-5, -18)
• (-5, 8)

Alexandra finds that she can give 3 haircuts and 2 hair dyes in 315 minutes. Giving 2 haircuts and 4 hair dyes takes 450 minutes.  Which system of equations represents the situation?

• 3x + 2y = 315
  2x + 4y = 450
• 3x + 2y = 450
  2x + 4y = 315
• 2x + 2y = 315
  3x + 4y = 450

• ( -3, 3, -2)

Does the equation open or or down? Is the vertex a maximum or minimum?

Y = -3x² +7x - 2

• up, minimum

• down, maximum

• up, maximum

• down, minimum
