Please help me with this problem

9xy = 3x . 3y

2xyz = 2x . y . z

4x . 4y = 16xy

1, 4, 5.

Step-by-step explanation:

1. 3x * 3y is equal to 9y.

4. 2x * y * z is equal to 2xyz, since the grouped variables mean the same thing as multiplied.

5. 4x * 4y is 16xy, because 4 * 4 is 16 and x * y is xy.

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

tube or goog would be a great resource to with that question
