A publisher needs to send many books to a local book retailer, and will send the books in a combination of small and large boxes. Each small box can hold 20 books and each large box can hold 45 books. How many books could be shipped using 5 small boxes and 7 large boxes? How many books could be shipped using ss small boxes and ll large boxes?

415 books, I dont understand the second question, sorry

Step-by-step explanation:

1 small box=20 books

1 big box=45 books

5 small boxes×20 books= 100 books

7 large boxes×45 books= 315 books

315 books+100 books=415 books

985

Step-by-step explanation:

45(5)+95(8)

225+760

225+760=985

s small boxes and l large boxes:

45+95

45s+95l

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
