The hart family drove 10 hours to their vacation spot. they drove an average of 48 miles each hour. how miles did they drive in all

They drove 480 miles in all.

Step-by-step explanation:

The formula use to find distance :-

Given : The hart family drove 10 hours to their vacation spot.

i.e. Time = 10 hours

They drove an average of 48 miles each hour.

i.e. Speed = 48 miles each hour

Then,

Hence, they drove 480 miles in all.

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

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

therefore the required function is . the graph of this function is shown below.
