Answer:

7f

Step-by-step explanation:

<em>To</em><em> </em><em>simplify</em><em> </em><em>you</em><em> </em><em>will </em><em>need</em><em> </em><em>to</em><em> </em><em>do</em><em> </em><em>it</em><em> </em><em>the</em><em> </em><em>same</em><em> </em><em>way</em><em> </em><em>as</em><em> </em><em>in</em><em> </em><em>adding</em><em> </em><em>natural</em><em> </em><em>numbers</em><em> </em><em>the</em><em> </em><em>variabl</em><em>e</em><em> </em><em>doesn't</em><em> </em><em>change </em><em>the</em><em> </em><em>number</em>

<em>So</em><em> </em><em>it</em><em>'s</em><em> </em><em>going</em><em> </em><em>to</em><em> </em><em>be</em><em>;</em>

<em>9</em><em>f</em><em>+</em><em>1</em><em>0</em><em>f</em><em>-</em><em>1</em><em>2</em><em>f</em>

<em>(</em><em>Nine</em><em> </em><em>plus</em><em> </em><em>Ten</em><em> </em><em>is</em><em> </em><em>equal</em><em> </em><em>to</em><em> </em><em>1</em><em>9</em><em>)</em><em> </em>

<em>•</em><em>T</em><em>h</em><em>e</em><em> </em><em>variable </em><em>remains</em><em> </em><em>the</em><em> </em><em>same</em>

<em>1</em><em>9</em><em>f</em><em>-</em><em>1</em><em>2</em><em>f</em>

<em>•</em><em>S</em><em>o</em><em> </em><em>you</em><em> </em><em>subtract</em><em> </em><em>1</em><em>2</em><em> </em><em>from</em><em> </em><em>1</em><em>9</em><em> </em><em>which</em><em> </em><em>is</em><em> </em><em>going</em><em> </em><em>to</em><em> </em><em>be</em><em>;</em><em> </em>

<em>7</em><em>f</em>

Answer:

The inverse function of f(x)=2.5*x+150 is f⁻¹(x)=\frac{2}{5}x-60

Step-by-step explanation:

An inverse or reciprocal function of f (x) is called another function f ⁻¹(x) that fulfills that:

If f(a)=b then f⁻¹(b)=a

That is, inverse functions are functions that do the "opposite" of each other. For example, if the function f (x) converts a to b, then the inverse must convert b to a.

To construct or calculate the inverse function of any function, you must  follow the steps below:

Since f (x) or y is a function that depends on x, the variable x is solved as a function of the variable y. And since inverse functions swap the input and output values ​​(that is, if f (x) = y then f⁻¹(y) = x), then the variables are swapped and write the inverse as a function.

You know that he function f(x) = 2.5*x + 150 or y=2.5*x +150

Solving for x:

2.5*x +150=y

2.5*x= y-150

x=\frac{y-150}{2.5}

x=\frac{y}{2.5}-\frac{150}{2.5}

x=0.4y-60=\frac{2}{5}y-60

Exchanging the variable, you obtain that <u><em>the inverse function of f(x)=2.5*x+150 is f⁻¹(x)=</em></u>\frac{2}{5}x-60<u><em></em></u>
