Answer: 
Step-by-step explanation:
Find the x-coordinate of the vertex with this formula:
In this case:
Substituting values, we get:
Now we can substitute the coordinates of the vertex into the equation 
and then solve for "c".
Then:
The solution is D.
By plugging the x value, 5, into the equation:
6*5=30
30+1=31
y=31
the x value is 5 and the y value is 31
(5, 31)

Hope this helps!!
there were D. 1163 books left on the shelves or in circulation.
///////////////////////////////////////////////////////////////////////////
let us count the number of books that are NOT on the shelves now.
1st step: 32 + 24 = 56
2nd step: <em>the total number of books minus the amount of books that are damaged or out: </em>1,219 - 56 = 1163
