Josh has 36 postcards from national parks he visited. He wants to put them in a binder. Each page in the binder holds 4 postcards. How many pages does he need for
the binder? Explain.

He needs 9 pages

Step-by-step explanation:

8 will be full and 1 will have 2 extra

36 divided by 4

8 with 2 left over so 9 pages

he needs nine pages

Step-by-step explanation:

36 divided by 4 makes 9

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
