PLEASE HELP. ITS TIMED. Which pair shows equivalent expressions? 2x+10=-2(x-5)
0 -2(x+5) = 2x-10
-2x-10=-2k+5)
0 -2(x-5)=-2x-10

i'm not sure i quite understand, could you provide more information?

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

step-by-step explanation:

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.
