Answer:

\\ ln(x^2) - ln(x^2 + 1).

For values of x>0, it can be rewritten as \\ 2ln(x) - ln(x^2 + 1).

Step-by-step explanation:

For the expression:

\\ ln(\frac{x^2}{x^2 + 1})

We can apply this logarithmical property: \\ ln(\frac{x}{y}) = ln(x) - ln(y).

Then,

\\ \frac{x^2}{x^2 + 1} = ln(x^2) - ln(x^2 + 1).

If we assume values of <em>x </em>> 0 (non negative values for x), then the expression could be rewritten as follows:

\\ \frac{x^2}{x^2 + 1} = ln(x^2) - ln(x^2 + 1) = 2 ln(x) - ln(x^2 + 1), since \\ ln(x^{n}) = n*ln(x).

We have to remember that <em>domain</em> (all possible values x) for logarithmic function is for all x > 0, or mathematically expressed as:

Domain: \\ {x | x \in R, x > 0}

Sole the system by elimination -4x+9y=9 x-3y=-6
Natalka [10]

Answer:

A) -4x + 9y = 9

B) x -3y = -6

We multiply B) by 3

B) 3x -9y = -18 Then add it to A)

A) -4x + 9y = 9

-x = -9

x = 9

9 -3y = -6

3y = 15

y = 5

Consider the function.
Licemer1 [7]

Answer:

Option 4

Step-by-step explanation:

Given function is,

f(x)=2\frac{1}{2}-3\frac{1}{3}x

Steps to get the inverse of the given function,

Step 1,

Convert the function into equation,

y=2\frac{1}{2}-3\frac{1}{3}x

Step 2,

Interchange the variables 'x' and 'y',

x=2\frac{1}{2}-3\frac{1}{3}y

Step 3,

Solve the equation for the value of y,

x-2\frac{1}{2}=-3\frac{1}{3}y

x-\frac{5}{2}=-\frac{10}{3}y

-x+\frac{5}{2}=\frac{10}{3}y

-3x+\frac{15}{2}=10y

-\frac{3}{10}x+\frac{15}{20}=y

y=-\frac{3}{10}x+\frac{3}{4}

Step 4,

Convert the equation into inverse function,

f^{-1}x=-\frac{3}{10}x+\frac{3}{4}

For x-intercepts,

Substitute y = 0,

0=-\frac{3}{10}x+\frac{3}{4}

\frac{3}{10}x=\frac{3}{4}

x=\frac{10}{4}

x=\frac{5}{2}

x=2\frac{1}{2}

Therefore, x-intercept of the inverse function is (2\frac{1}{2},0).

Option 4 will be the answer.
