F(x) = 9x + 3<br>g(x) = 3x + 1<br>Find:<br>(f/g)(x)​
igomit [66]

Answer:

<h2>(f/g)(x) = 3</h2>

Step-by-step explanation:

f(x) = 9x + 3

g(x) = 3x + 1

To find (f/g)(x) divide f(x) by g(x)

That's

(f/g)(x) =  \frac{9x + 3}{3x + 1}

Factorize f(x)

f(x) = 9x + 3 = 3(3x + 1)

So we have

(f/g)(x) =  \frac{3(3x + 1)}{3x + 1}

Simplify

We have the final answer as

<h3>(f/g)(x) = 3</h3>

Hope this helps you

$260

I don’t know what model/formula you are supposed to be using.

But what I did first was calculated what 30% of 2700$ is.
2700 x .3 = 810

So it depreciates $810 per year.

$810 x. 3 years = 2430

2700 - 2430 = 260

In three years, the laptop will be worth $260
