Pretty Sure it’s y=x+(-.8) haven’t done algebra in a bit. Sorry if wrong. :/
You have

So, we have to compute g(7) and feed it as input to f(x). We have

Answer:
if she does so multiply by seven to get final answer
Answer:
x = 2/9
Step-by-step explanation:
3x = 2/3
3*3x = 2
9x = 2
x = 2/9
Check:
3*2/9 = 2/3
6/9 = 2/3
A) No, the root 3 has multiplicity of 3.
B) No, there are two imaginary solutions.
C) No, the root −2 has multiplicity of 3.
D) Yes, the Fundamental Theorem of Algebra does not apply to this equation.
