Answer:
ok the train goes 60+80=140 in 1 hour
140+140=280 2 hours
392-280=112
112/ the 60 miles and 80 miles is .80% of the hour so
60*.80=48 and 80*.80=64
48+64=112 so the trains will be 392 miles apart in 2.8 hours
Step-by-step explanation:
let this happens after t hours
so
80t + 60t = 392
140 t = 392
t = 392/140
=2.8 hours
-6, because you can see a pattern in which the x coordinate of each pair is reversed to the opposite value, from positive to negative.
Letter B
f(2) is greater than g(2) and f(-2) is less than g(-2)
