Answer:
8.04
Step-by-step explanation:
Solution 1
x= r- 4.5= 25.2/2 - 4.5= 8.1
Solution 2
x= √(25.2/2)² - 9.7²= √64.67= 8.04

Slope is
Then you use the equation
Where b is the y-intercept. To find it, plug in x and y from one of the points. Say, point 1 (1,10):
You know m (from above) and now you can solve for b.
Rearrange terms:
And that will be the answer.
Make sense?

The cost function is an illustration of a linear function
The equation of the cost function is C(x) = 35 + 0.5x
The given parameters are:
-- the cost of renting a cooler
--- the rate per bottle
Assume the number of bottles in a cooler is x.
The cost function for the bottles in a cooler would be:
So, we have:
Evaluate the products
Hence, the equation is
