Answer:
The faster train goes 60mph
Step-by-step explanation:
s= speed
s+20 is the faster train.
Then you are given:
200/s+s+20=2
200=2*(2s+20)
4s+40=200
4s=160
s=40 is the slower train
40+20= speed of faster one
s=60 ;)

Y=-3 on the graph question
Equation for the parallel line through (9,-11) is y=-2/3x-5
The slope intercept form of -8x=2-2y is y=4x+1
The equation of a perpendicular line through (15,8) is y=-7/5x+29 :)
