If one book = 1/8, then you can just multiply it by 3, for the three mystery books. 8x3= 24, so tony has 24 books in all.

Is this a funtion? please help
creativ13 [48]

Answer:

No, it is not

Step-by-step explanation:

Here, we want to check if what we have is a function

For a relation to be a function, the mapping must be one to one or many to one

This mean, for every x there must be one y or for every y, there must can be multiple x

But never is it that there are many y for a single x

Looking at the value 0

on the domain, we can see -2 and 1 as the values

Thus, this is not a function

Find the menu for your favorite pizza place. Calculate the price per square inch for a small, medium, and large pizza. Which is
ankoles [38]
Look up a Pizza Place Online; with a website preferably 
Find the cost and diameter of each size (should be in any pizza menu)
Divide the diameter by the cost (Cost/Diameter)
ex: 4.99/12
=0.415833333 per inch 
Do this for all the sizes and compare each of the sums.
The one with the lowest cost per inch would be the best deal.
 
Hope this helps!
