Answer:
x = 7.5
Step-by-step explanation:
Since we see that sides AD and DC are equal, as well as sides BE and EC, we can use this information to conclude that the value of 2x-7 is equal to double the value of DE.
2x - 7 = 4(2)
2x - 7 = 8
2x - 7 + 7 = 8 + 7
2x = 15
x = 7.5
it is definitely the answer B
Constant rate means it is linear so we don't have to worry about fluctuation.
change in y/ change in x=-18-(-25.2)/5-8=2.4 meters per second
