At the local grocery store, cans of beans are arranged in rows. the number of cans in each row forms an arithmetic sequence. there are 93 cans in row 1, 88 cans in row 2, 83 cans in row 3, and so on. one row contains 48 cans. which row is this?

c. 4 and 1/2 pounds is the answer! : )

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
