Find the inverse function (find f^-1)

Reil [10]

Step-by-step explanation:

f(x) = (x-2)/(3x+3). Let y = f(x).

Then y = (x-2)/(3x+3).

y(3x+3) = x - 2

3xy + 3y = x - 2

3xy - x = -3y - 2

x(3y-1) = -(3y+2)

x = -(3y+2)/(3y-1)

Hence, the inverse of f(x) is -(3x+2)/(3x-1).

In a random sample of 30 sixth graders, 9 had traveled outside of the United States. There are a total of 120 sixth graders in t

36 students have traveled outside of the United States, when there are total 120 sixth graders.

<u><em>Explanation</em></u>

The number of students traveled outside of the United States is 9 when there is total 30 sixth graders. So, the ratio of the student traveled to the total students will be $9: 30 = 3: 10$

Now there are total of 120 sixth graders in the school and lets assume the number of students traveled outside the United states is $x$ . That means the ratio...

$x: 120 = 3:10 \\ \\ \frac{x}{120}=\frac{3}{10} \\ \\ 10x=360\\ \\ x=\frac{360}{10} \\ \\ x= 36$

So, 36 students have traveled outside of the United States.
