Astate has a limit on the lengths of cargo trains. the train cannot exceed a length of 1,100 ft. train a has 28 cars at 40 feet each, and train b has 34 cars at 30 feet each. do the trains meet the requirement?

Part a : solve -vp + 40 < 65 for v part b : solve 7w - 3r = 15 for r show your work .

If f(x) = 2x - 6 and g(x) = 3x + 9, find (f - g)(x). a. (f-g)(x) = x + 15 o o b. (f- g)(x) = -x - 15 o c. (f- g)(x) = 5x + 3 o d. (f- g)(x) = -x+3 submit

1. a parachutist is 800 feet above the ground when she opens her parachute. she then falls at a constant rate of 5 feet per second. select the equation that represents this situation. h = -800t + 5 y = -5x + 800 h = 5t - 800 y = 800x + 5 i need
