Factor the expression using the GCF 2x + 10 may you ask so explain how to get the answers? Thank you

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

you would need to know all the numbers that are on there

step-by-step explanation:

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5
