Billy stacked six pieces of wood on top of one another .if each piece was three-quarters of a foot tall, how tall was his pile?

each piece is 0.75 feet (3/4 of a foot) and there are six pieces

multiply 0.75 by six

=4.5feet

therefore his pile was 4.5 feet tall

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
