1) A mail truck can transport no more than 3200 pounds (lbs.) with a volume of no more than 500 cubic feet (ft3). The truck transports two sizes of packages. The small package has a weight of 20 lbs. and a volume of 4 ft. The large package weighs 60 lbs. and has a volume of 10 ft. Let x be the number of small packages and y be the number of large packages. Write a system of inequalities to represent the situation. (Make sure to simplify each inequality by dividing out any common factors.)

(01.03 mc) which of the following is a step in simplifying the expression x multiplied by y to the power of 2 over x to the power of negative 3 multiplied by y to the power of 3, the whole to the power of negative 4. select one: a. x to the power of negative 4 multiplied by y to the power of negative 2, the whole over x to the power of negative 7 multiplied by y to the power of negative 1. b. x to the power of negative 4 multiplied by y to the power of negative 8, the whole over x to the power of 12 multiplied by y to the power of negative 12. c. x to the power of negative 4 multiplied by y to the power of negative 8, the whole over x to the power of negative 3 multiplied by y to the power of 3. d. x to the power of negative 4 multiplied by y to the power of negative 2, the whole over x to the power of negative 3 multiplied by y to the power of 3.
