Your goal is to run a mean of 45 minutes per day for a week. for the first six days, you run 38, 40, 40, 42, 43, and 50 minutes. how many minutes must you run on the seventh day to reach your goal exactly?

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

could you reply to this with the question so i can ?
