Robert is already 50 miles from his home on his way to the game he is driving 55 miles per an hour write an equation that models this

d = 50 + 55t

Step-by-step explanation:

We consider that we have to model the relation between the distance from his house towards his play, d in miles after time t, in hours from the present.

Given that Robert is already 50 miles from his home on his way to the game and he is driving 55 miles per hour.

Therefore, at t = 0, d = 50 miles which is the initial value of the linear function and the rate of change of his position with respect to time is 55 miles per hour.

Hence, d = 50 + 55t is the requires equation. (Answer)

10

step-by-step explanation:

7+3=10

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
