I need help solving one variable equations !! example i could use but need an answer to:
5 + y = 7

is it just replacing the variable with the number that would sum it all together?

the answer is y=2

Step-by-step explanation:

Doing 1-multiple step equations to figure out the variables you have to remove the number on the left side which in this situation is 5 you subtract 5 on both sides 5 and 7 so the left side becomes 0 and the right side becomes 2 if u have anymore questions feel free to ask :))! And I hope this helps

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

its not b
