Answer:

Step-by-step explanation:
So we have the function:

To solve for the inverse of a function, change f(x) and x, change the f(x) to f⁻¹(x), and solve for it. Therefore:

Add 9 to both sides:

Take the natural log of both sides:

The right side cancels:

Divide both sides by 6:

And we're done!
Answer:
Cross Multiply
Step-by-step explanation:
1. Multiply 16 by 9 and you get 144
2. Multiply 5 by x
This is called cross multiplying.
3. Set up the equation. 5x=144
144/5=28.8
x=28.8
The first answer is C
The second answer is C
The third answer is B
