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 ;)
0.2 (y+2) = 0.2y + 0.2(2)
= 0.2y + 0.4

Answer:
y = x +2
Step-by-step explanation:
4y=4x+8
Slope intercept form is
y = mx+b so we need to solve for y
Divide each side by 4
4y/4 = 4x/4 +8/4
y = x +2
The slope is 1 and the y intercept is 2
