The yearly cost y for driving a certain car is $7,800 for 10,000 miles

and $11,400 for 20,000 miles. Let x be the number of miles driven

in a year

Write a linear function that models this data. Then use the function to find the given value.

y=

(Simplify your answer and round to TWO decimal places, including zeros as needed. Example: 2 should be written as 2.00. Do not include commas.)

Estimate the number of miles driven when the yearly cost is $9,636.00.

miles

(Round your answer to TWO decimal places, including zeros as needed.

Example: 2 should be written as 2.00. Do not include commas.)

y = 0.36x + 4200.00

15100.00 miles.

Step-by-step explanation:

If the yearly cost for driving x miles is given by y dollars then the two ordered pairs to find the linear relation between x and y are (10000,7800) and (20000,11400).

So, the equation will be

⇒

⇒

⇒

⇒ y = 0.36x + 4200.00 ........... (1) (Answer)

Now, for y = $9636.00, from equation (1),

9636 = 0.36x + 4200

⇒ 0.36x = 5436

⇒ x = 15100.00 miles. (Answer)

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,
