What is the greatest common factor of the terms in the expression 7/3ab minus 7/6b?
A. 1/3b
B. 1/3a b
C. 7b
D. 7ab

7/3 b

Step-by-step explanation:

7/3 ab - 7/6 b

7/3 b *a  - 7/3*2 b

We can factor out 7/3 b from each term

7/3 b (a - 1/2)

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
