D=rt solve by setting up a system of linear equations with 2 variables and 2 unknowns. a jeep and a bmw enter a highway that runs east-west at the same exit heading in opposite directions. the jeep entered the highway 30 minutes before the bmw entered the highway, and traveled 7 mph slower than the bmw. after 2 hours from the time the bmw entered the highway, the cars were 306.5 miles apart. find the speed of each car, if they were driven on cruise control

(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.
