Acar travels at a rate of 45 miles per hour for 5 hour. let y be the distance , in miles , the car travels for a given amount of time ,x, in hours. the situation can be modeled by a function. which of these describe the domain of the function

Step-by-step explanation:

The complete question in the attached figure

Let

x ----> the time in hours

y ----> the distance in miles

In this problem we have a proportional relationship between the variables x and y

The linear equation is of the form

The slope or unit rate is the same that the constant of proportionality k

The constant of proportionality is the speed of the car

so

substitute

Convert to function notation

The domain of the function is the interval ---> [0,5]

All real numbers greater than or equal to 0 hours and less than or equal to 5 hours

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
