Both equations are equivalent, so there are infinitely many solutions.
Well it depends on what the model is but if it's an IRA or whatever so if you make your own model that's easy
Answer:
Step-by-step explanation:
a) The domain is R- all real numbers.
b) The domain is R- all real numbers.
c) we need

So the domain is R\{-2, 2}
d)
we need

So the domain is R\{-2, 1}
e)
we need: x-1>0 or x> 1
So the domain is (1,+∞)
A because the 6 and 3 cancel out
Then 2 x 8 is (16) and 15 x 5 is (75)
Making it A
