EOC Review for Faculty

David is running a concession stand at a soccer game. He sells nachos and sodas. Nachos (x) cost $1.50 each and sodas (y) cost $0.50 each. At the end of the game, David made a total of $78.50 and sold a total of 87 nachos and sodas combined. Which system of equations represents this situation?

• 1.5x + 0.5y = 78.5
  x + y = 87

• 1.5x + 0.5y = 78.5
  1.5x + 0.5y = 87

• x + y = 78.5
  1.5x + 0.5y = 87

• x + y = 78.5
  x + y = 87

Match the system of inequalities to the graph.

• y ≥ -x - 1 and y ≥ x + 4

• y < -x - 1 and y ≥ x + 4

• y > -x - 1 and y ≥ x + 4

• y > -x - 1 and y > x - 4

Mookie Betts hits a fly ball. You can track the height of the ball using the equation:

h(t) = -16t² + 140t + 2

What was the starting height of the ball?

• -16 feet

• 140 feet

• 2 feet

• 0 feet

Chandler drops a ball from a third-story window. The equation, h(t) = -5t² + 45  represents the approximate height, h, in meters, of the ball above the ground after it falls for t seconds.
When does the ball hit the ground?

• t = 0 seconds 

• t = 3 seconds

• t = 9 seconds

• at both t = 0 seconds and t = 3 seconds

What percentage of The Cruisers attended less than 13 car shows?

• 25%
• 50%
• 75%
• 100%

Solve for x:

• x = yb - v
• x = by - v
• x = by + v

Determine the function rule.

• y = 5x - 4

• y = 5x + 4

• y = 4x + 5

• y = 4x - 5

You bought a new boat to enjoy for the summer. The function 26,000(.86)^x models the value of the boat x years after it's purchase. At what rate is the value of the boat changing?

• The value is decreasing by 86% each year

• The value is decreasing by 14% each year

• The value is increasing by 14% each year

• The value is increasing by 86% each year

• infinitely many solutions

• no solutions

• The graph of the original function is steeper than the graph of the new function.

• The graph of the original function is parallel to the graph of the new function.

• The graphs intersect at (4, 0).

• The graphs intersect at (0, 4).
