On thursday you ran to a playground 2 1/4 mi. from your house. it took you 19 min. to run there and 20 minutes to run back home. on friday you ran the entire4 1/2 mile at a constant speed of 6 1/4 mi/h. how many minute did it take you to run on thursday?

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
