We can use the distributive property to simplify this expression.
I split this up into different parts--it helps me visualize better.
To begin, "-2m(m + n - 4)" becomes "-2m^2 - 2mn + 8m"
Then, "5(-2m + 2n)" becomes "-10m + 10n"
Finally, "n(m + 4n - 5)" becomes "mn + 4n^2 -n"
We can then simplify even further by combining like terms. The final expression is: C

<u>Step-by-step explanation:</u>
An inverse function is a function that "reverses" another function: if the function f applied to an input x gives a result of y, then applying its inverse function g to y gives the result x, and vice versa, i.e., f(x) = y if and only if g(y) = x. As an example, consider the real-valued function of a real variable given by f(x) = 5x − 7. In functional notation this inverse function would be given by,
![{\displaystyle g(y)={\frac {y+7}{5}}}](https://tex.z-dn.net/?f=%7B%5Cdisplaystyle%20g%28y%29%3D%7B%5Cfrac%20%7By%2B7%7D%7B5%7D%7D%7D)
With y = 5x − 7 we have that f(x) = y and g(y) = x. Here we have ![f(x) = \frac{x-7}{x}](https://tex.z-dn.net/?f=f%28x%29%20%20%3D%20%5Cfrac%7Bx-7%7D%7Bx%7D)
![f(x) = \frac{x-7}{x}](https://tex.z-dn.net/?f=f%28x%29%20%20%3D%20%5Cfrac%7Bx-7%7D%7Bx%7D)
⇒ ![f(x) = \frac{x-7}{x}](https://tex.z-dn.net/?f=f%28x%29%20%20%3D%20%5Cfrac%7Bx-7%7D%7Bx%7D)
⇒ ![f(x) =1- \frac{7}{x}](https://tex.z-dn.net/?f=f%28x%29%20%20%3D1-%20%5Cfrac%7B7%7D%7Bx%7D)
Let f(x) = y:
⇒ ![f(x) =1- \frac{7}{x}](https://tex.z-dn.net/?f=f%28x%29%20%20%3D1-%20%5Cfrac%7B7%7D%7Bx%7D)
⇒ ![y = 1 - \frac{7}{x}](https://tex.z-dn.net/?f=y%20%3D%201%20-%20%5Cfrac%7B7%7D%7Bx%7D)
⇒ ![y -1 = \frac{-7}{x}](https://tex.z-dn.net/?f=y%20-1%20%3D%20%5Cfrac%7B-7%7D%7Bx%7D)
⇒ ![x = \frac{-7}{y-1}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B-7%7D%7By-1%7D)
