Answer:

Option D.

Step-by-step explanation:

The slope of a horizontal line is 0.

It is given that the function 1 is a horizontal line that passing through the y-axis at y = 4.

It means the rate of change of function 1 is 0.

The slope intercept form of a linear function is

y=mx+b            .... (1)

where, m is slope and b is y-intercept.

The function 2 is

y=8x+12           .... (2)

On comparing (1) and (2), we get

m=8

The rate of change of function 2 is 8.

The difference between rate of change is

8-0=8

The rate of change of function 2 is 8 more than the rate of change of function 1.

Therefore, the correct option is D.

Answer:

7:55 am

To determine the time needed to leave, add up all of the elapsed time and subtract that from the 8:50 departure time. The 10 minutes from walking to the platform puts us at 8:40 am, 30 minutes to reach the station puts us at 8:10 am, and the extra 15 minutes gives a time of 7:55 am.
