the temperature in anchorage Alaska was -18 . a scientist recorded the change in temperature over the next 5 hours. the increases and decreases in temperature can be represented as -3, +7, +11, -5, +2, what was the temperature in anchorage alaska after 5 hours?

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
