An office supply store scans document pages. The store charges the same amount for each scanned page and a one-time charge for the scan of any number of pages. The equation below gives the total cost of scanning x document pages. y=0.10x+0.25 What does 0.25 represent in this problem?

0.25 = one time charge

Step-by-step explanation:

Given that:

Charging pattern of store for scanning documents :

(One time fee + fixed amount per page scanned)

The equation:

y=0.10x+0.25 ; gives the total cost of scanning x document pages

Comparing the equation and the charging pattern :

y = total cost

0.10 = fixed cost per page

x = number of pages scanned

0.25 = one time charge(not dependent on number of pages to be scanned).

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.
