The value of x is 5.4 ( find the description in the picture)
Y = 1/(x - -2)
y = 1/(x + 2)
I moves the graph 2 units to the left
y-intercept is -6 (0,-6) and the x-intercept is -3 (-3,0)
Lengthof train=X
platform length=180
total distance=x+180
speed=60km/hr=60×5/18=(300/18)m/
Time =18s
Time =Distance/speed
18=X+180/(300/18
18×300=18(X+180)
300=X+180
x=300-180=120
so length of the train=120m
