• -2 and 3
• -1/2 and -6
• -2 and -6
• 3 and -6

Solve
2x² + 17x + 21 = 0

• x= ^-21/₂, -17
• x= ²/₃, 16
• x=-7, ^-3/₂
• x=15, -³/₇

Solve the system by graphing:
y = 6x - 4
y = -x + 3

• (1, 2)
• (2, 1)
• (4, 5)
• (2, 4)

Complete the Square and write in Vertex Form:
f(x) = x² + 6x + 5

Graph the 1st problem.

Graph the answer choices and match!!!

• (x + 3)² - 4
• (x + 6)² - 4
• (x + 3x)² - 4
• (x + 3)² + 9

What are the Zero's of the following: x² + 3x - 18 = 0

Zero's/Roots/Solutions/x-intercepts are all the same!!!

• x = -3 and x = 6
• x = 3 and x = -6
• x = -9 and x = 2
• x = 9 and x = -2

The talent show committee sold a total of 530 tickets in advance. Student tickets cost $3 each and the adult tickets cost $4 each. If the total receipts were $1740, how many of each type of ticket were sold?

• S + A = 530
  3S + 4A = 1740
• S + A = 530
  4S + 3A = 1740
• S + A = 1740
  3S + 4A = 530
• S + A = 1740
  4S + 3A = 530

The prices of two gyms are graphed. Which statement below best represents the solution?

• Both gyms cost $90 for 10 classes

• Both gyms cost $10 for 90 classes

• Both gyms charge $60 to start

• Both gyms cost $20 before taking any classes.

Flagship Cinemas sells movie tickets that are $4 for matinees and $7 for regular. One night, the theater sells 578 tickets and collects $3365 in total ticket sales.
Which system best represents the situation?

• 4x + 7y = 578
  x + y = 3365
• 4x + 7y = 3365
  x + y = 578
• 4y + 7x = 578
  x + y = 3365
• 4y + 7x = 3365
  x + y = 578

The graph of a quadratic function is shown on the grid.
