Answer: Simplified form will be

\frac{(x-5)}{(x-4)}

Explanation:

Since we have given that

\frac{5x^2-21x-20}{5x^2-16x-16}

We need to simplify the expression, we get,

\frac{5x^2-25x+4x-20}{5x^2-20x+4x-16}\\\\\text{We will split the middle terms}\\\\=\frac{5x(x-5)+4(x-5)}{5x(x-4)+4(x-4)}\\\\=\frac{(5x+4)(x-4)}{(5x+4)(x-4)}\\\\\text{ Cancel the common terms}\\\\=\frac{(x-5)}{(x-4)}

Hence, simplified form will be

\frac{(x-5)}{(x-4)}

Answer:

The value of k is -2

Step-by-step explanation:

The cut point with the y axis for both graphs occurs when x = 0

We then have:

For f (x):

The cut point for the y axis is:

For g (x):

The cut point with the y axis is:

The value of k is given by the vertical displacement of graph k units.

We then have:

What is inverse notation?
Hitman42 [59]

In mathematics, an inverse function (or anti-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, f(x) = y if and only if g(y) = x.
