What two numbers multiplies to -225 but adds to 16

first you do -225+16 which equals -209

then you dived it by 2 which is not a whole number

then you go to 3 - no

4 - no

5 -no

6-no

7-no

8-no

9-no

10 - no

11 - yes    

so theequation is

11* (-19) +16 = -225

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
