Answer:
0
Step-by-step explanation:
A number (besides 0) plus its opposite will always be zero.
for example:
-8=opposite is 8
8+-8=0
If the traslation is T(x,y)=(x-1,y+1) then:
Therefore A'=( -7,3).
The two trains will meet when the sum of the distances covered by the two trains is 504 miles.
distance = speed x time.
Let the time covered when they meet be x, then:
80x + 100x = 504
180x = 504
x = 504/180 = 2.8.
Therefore, the two trains will meet in 2 hours 48 mins.
