Is the answer to your question 9?
Answer:
X=-1,y=-2
Step-by-step explanation:
if y =2x
2x=4x+2
so X=-1 and y=-2
Since CB || ED and CB = ED,
by the alternate interior angles theorem,
mE = mC, and mD = mB.
with CB = ED, we can conclude that CBF = EDF, by SAS congruent theorem.
X=3
g(3)=3+4=7
f(g(3))=f(7)=78
f(g(3))f(g(3))=6084
is this the correct answer?
