Step-by-step explanation:
I will solve your system by substitution.
3y−3=3x; −3x+3y=−57
Step: Solve 3y−3=3x for y:
3y−3+3=3x+3 (Add 3 to both sides)
3y=3x+3
(3y/3=3x+3)/3
(Divide both sides by 3)
y=x+1
Step: Substitute x+1 for y in −3x+3y=−57:
−3x+3y=−57
−3x+3(x+1)=−57
3=−57 (Simplify both sides of the equation)
3+(−3)=−57+(−3) (Add -3 to both sides)
0=−60

Answer:
C
Step-by-step explanation:
It's stated that EFI is dilated by a scale factor of 1/3.
Dilating gives the following
FH = 1/3×FE
FG = 1/3×FI
HG = 1/3×EI
Sense ΔEFI is reflected over a line FG/FH = (1/3×FI)/(1/3×FE) = FI/FE
Notice that the following shows triangle similarity, meaning ΔEFI ~ ΔHFG.
The only answer choice that shows this would be FE/3 = FH, FI/3 = FH, and
EI/3 =HG ΔEFI ~ ΔHFG.
