Answer:
<em>Correct answer:</em>
<em>A. I and II</em>
<em></em>
Step-by-step explanation:
First of all, let us have a look at the steps of finding inverse of a function.
1. Replace y with x and x with y.
2. Solve for y.
3. Replace y with 
Given that:

Now, let us find inverse of each option one by one.
I. y = x, a(x) = x
Replacing y with and x with y:
x = y
x =
=
Hence, I is true.
II. 
Replacing y with and x with y:

=
Hence, II is true.
III. 
Replacing y with and x with y:
Hence, III is not true.
IV. 
Replacing y with and x with y:
Hence, IV is not true.
<em>Correct answer:</em>
<em>A. I and II</em>

Answer:
There is no image.
Step-by-step explanation:
Can you add a image or something because You did not give a "line below"
2(6.02*10^23)(3.35*10^-23)
2*6.02*3.35
answer : 4.0334*10^1
It would have an infinite amount of solutions.
Change each equation into y=mx+b form and then do system of equations.
