Given:

The function is:

$f(x)=-2x+5$

To find:

The inverse of the given function, then draw the graphs of function and its inverse.

Solution:

We have,

$f(x)=-2x+5$

Step 1: Substitute $f(x)=y$ .

$y=-2x+5$

Step 2: Interchange x and y.

$x=-2y+5$

Step 3: Isolate variable y.

$2y=5-x$

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

Step 4: Substitute $y=g(x)$ .

$g(x)=\dfrac{5-x}{2}$

Hence, the inverse of the given function is $g(x)=\dfrac{5-x}{2}$ and the graphs of these functions are shown below.

Step-by-step explanation:

Our equation is:

$\left(1x-5y\right)-1\left(x+2y\right)$

First we dritribute

Now we have, $x-5y-x-2y$

$Combine$ light terms

and we get $-7y$

Answer:

5/17

Step-by-step explanation:

If we do the multiplication first, we get:

$\frac{4-(12\div-12)}{13+(-8\div-2)}$

If we do the division next, we get:

$\frac{4+1}{13+4} = 5/17$
