Meg is a veterinarian. She found that 7, or 50%, of the dogs she saw this week were boxers. Steve is also a veterinarian. He found that 25% of the 20 dogs he saw this week were boxers. Does each person need to find the part, the whole, or the percent?

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
