Answer:
x=-17
y=-2 2/3
Step-by-step explanation:
start with the second one and do substitution
x -6y=-1 add the -6y over to get x alone
x=6y-1 put this into first equation
2(6y-1)-15y=6 distribute
12y-2-15y=6 add like terms
-3y-2=6 add the -2 over
-3y=8 divide by -3
y=-2 2/3 put this back into the first equation that was solved for x
x=6(-2 2/3)-1 distribute
x=-17
Let's prove triangle DEF:
10/7=1.428571429 different to 1.5=9/6, then triangle DEF is not similar to triangle ABC
Let's prove triangle GHI:
3.5/7=0.5=3/6, then triangle GHI is similar to triangle ABC
Answer: Option B. GHI
