Amelia bought 9/12 pound of sliced salami at the deli counter. which of the following decimals did the scale show,
a. 0.25 pounds
b.0.34 pounds
c.0.7 pounds
d.0.75 pounds,
say how and explain

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
