Hot dogs and bags of popcorn were sold at a concession stand. One family paid $8.00 for 2 hot dogs and 3 bags of popcorn. Another family paid $16.50 for 5 hot dogs and 4 bags of popcorn. Which system of equations can be used to determine the price in dollars of a hot dog, x, and the price in dollars of a bag of popcorn, y?

• 2x + 5y = 8

  3x + 4y = 16.5

• 5x + 4y = 8

  2x + 3y = 16.5

• 2x + 3y = 8

  5x + 4y = 16.5

• 3x + 2y = 8

  4x + 5y = 16.5

Which expression is a factor of x² + 7x - 30?

• x + 15

• x - 10

• x + 5

• x - 3

What is the solution to the equation 7w - 2(w - 9) = 4 - 8(w + 2)?

• w = -26/9

• w = 15/13

• w = -30/13

The graph of quadratic function h is shown on the grid. Which function is best represented by the graph h?

• h(x) = -x² - 8x - 15

• h(x) = -x² + 8x - 15

• h(x) = x² + 8x + 15

• h(x) = x² - 8x + 15
