At a holiday ski resort, skis cost $16 to rent and snowboards cost $19. If 28 people rented on a certain day and the resort brought in $478, which system could be used to determine the number of skis (s) and snowboards (b) rented?

• s+b=478
  19s+16b=28

• s + b = 28
  16s+19b=478

• s+b=478
  16s+19b=28

• s+b=28
  19s+16b=478

What is the domain of f(x)=9-x²?

• f(x) ≥ 9

• All real numbers

• -3 ≤ x ≤ 3

• x ≤ 9

A set of weights includes a 4 lb barbell and 6 pairs of weight plates. Each pair of plates weighs 20 lb. If x pairs of plates are added to the barbell, the total weight of the barbell and plates in pounds can be represented by f(x) = 20x + 4. What is the range of the function for this situation?

• {0, 1, 2, 3, 4, 5, 6}

• {4, 24, 44, 64, 86, 104, 124}
