Option D:

$y=\frac{5x-2}{x}

Solution:

Given function:

$y=\frac{-2}{x-5}

To find the inverse of the function.

<u>Inverse of a function:</u>

<em>If a function f(x) is mapping x to y, then the inverse function of f(x) maps y back to x.</em>

$y=\frac{-2}{x-5}

Interchange the variables x and y.

$x=\frac{-2}{y-5}

Now, solve for y.

Multiply both sides by (y - 5).

$x(y-5)=-\frac{2}{y-5}(y-5)

Cancel the common factors, we get

x(y-5)=-2

Divide by x on both sides.

$y-5=-\frac{2}{x}

Add 5 on both sides.

$y=-\frac{2}{x}+5

$y=-\frac{2}{x}+\frac{5}{1}

To make the denominator same, multiply the 2nd term by \frac{x}{x}.

$y=-\frac{2}{x}+\frac{5x}{x}

$y=\frac{-2+5x}{x}

$y=\frac{5x-2}{x}

Option D is the correct answer.

Given  : 0.386; 0.3; 0.683; 0.836.

To find : which Is greatest to least.

Solution :" We have given 0.386; 0.3; 0.683; 0.836.

In 0.386

Tenth place is 3 and hundredth place is 8

In 0.3

Tenth place is 3 and hundredth place 0

In 0.683

Tenth place is 6 and hundredth place 8

In 0.836.

Tenth place is 8 and hundredth place 3.

So, Greatest number is 0.836 ,

Least number is  0.3.
