45 cars=454
Divide 45 on both sides to get the average length of a single car
1 car = 10.01 ft
A 180 counterclockwise rotation about the origin followed by a reflection of the y-axis
Answer:
-60/7 or -8 4/7 would be the answer
5(5+x) = 6(6+4)
25+5x = 60
5x = 35
x = 7
-----------------
3(3+5) = 4(4+x)
24 = 16 + 4x
4x = 24-16
4x = 8
x = 2
The function d(t) represents the distance traveled by the train after t hours. d(5) is the total distance traveled by the train after 5 hours, which means 6:00 pm. The d(2) is the total distance traveled by the train after two hours, 3:00 pm. The expression d(5) - d(2) represents the total distance traveled by the train from 3:00 pm to 6:00 pm or for traveling at a constant speed for 3 hours.
