Dominik [7]

Answer:

A'(1, 0 ), B'(1, 2 ), C'(3, - 2)

Step-by-step explanation:

using the rule, add 3 to the x-coordinate and subtract 2 from the y- coordinate of the original points.

A' = (- 2 + 3, 2 - 2 ) = A'(1, 0 )

B' = (- 2 + 3, 4 - 2 ) = B'(1, 2 )

C' = (0 + 3, 0 - 2 ) = C'(3, - 2 )

dybincka [34]

Answer:

If the shelves  are 4/5 full, then the total number of books in the library is 1,040 books

Step-by-step explanation:

13 roll of bookcases

All the bookcases have four shelves

Total number of shelves = 4 x 13

                                        = 52 shelves

Each shelve holds 25 books each

Total number of books that can be in the shelves altogether = 52 x 25

                                                                                                    = 1,300 books

If the shelves  are 4/5 full, then the total number of books in the library is,

 4/5 x 1300

= 1,040 books
