Write the equation of the parabola in vertex form.

• y = -2(x - 2)² + 1

• y = -(x - 2)² + 1

• y = -(x + 2)² + 1

• y = -2(x - 2)² - 1

The vertex of a parabola is (3, 4) and it passes though the point (1, -12). Write the equation of the parabola in vertex form.

• y = -3(x - 3)² + 4

• y = -2(x - 3)² + 4

• y = -4(x - 3)² + 4

• y = -(x + 3)² + 4

On Monday Joe bought 10 cups of coffee and 5 doughnuts for his office at the cost of $16.50.  It turns out that the doughnuts were more popular than the coffee.  On Tuesday he bought 5 cups of coffee and 10 doughnuts for a total of $14.25.  Which equations could be used to determine the cost of the coffee? 

• 10c + 5d = 14.25
  5c + 10d = 16.50
• 10c + 5d = 16.50
  5c + 10d = 14.25
• c + d = 10
  5c + 10d = 16.50
• c + d = 5
  5c + 10d = 16.50

Erin is 3 years younger than twice Alex's age. Their ages combined are 33 years. How old are Alex and Erin. If x=Erin's age and y=Alex's age, choose the system that matches the situation.

• x + y = 33
  y = 2x - 3
• x + y = 33
  x = 2y - 3
• x + y = 33
  x = 3 - 2y
• x + y = 3
  x = 33 - 2y
