Answer:
son = 6 mother = 48
Step-by-step explanation:
Mother = m
son = s
m = 8s
m+6 = 9/2 * (s+6)
so
2(8s + 6) = 9(s +6)
16s + 12 = 9s + 54
16s - 9s = 54 - 12
7s = 42
s = 42/7 = 6 years old
so the mother is 8s = 8*6= 48 years old

Answer:
Should be B
Step-by-step explanation:
I believe you just move the point that lines converge down 8 and to the right 3. Then you multiply the x-value by -1.
The answer to your question is 3x to the second power -6x+x to the third power +4
the answer i gave you is not yet put in standard form yet though
