Answer:
The inverse will be:

Step-by-step explanation:
In order to find the inverse of the equation, we do a variable change, since we are finding the inverse, :



Now solve for y'.
First add 4 in both sides of the equation and change to the left y'.

= x + 4
Second divide by 9
/9 = (x + 4)/9
= (x + 4)/9
Now you will have to clear y, with the square root.
[/tex] =
Simplifying terms


You can check the answer by doing the evaluation of the following equation:
(f o
) (x)
substitute the equation for y' or inverse function 
f(
)
Now substitue the value into f(x)
You will have

=x
In calculating the mean of this data set Ashrita did the best job.
The Mean of the data set is the most commonly used measures of central tendency.
It means the average value of the data set.
one doesn't have to arrange the data in order for finding it.
<h3>What is the meaning of mean?</h3>
The data set value takes is to add them all together and divide that by the number of the data.
It can be written as

Where
are the values in the data set
Therefore we can conclude that Ashrita did the best job in calculating the mean of this data set.

Answer:
2/3 min
Step-by-step explanation:
We can write these as equations
so 8-2.5x=5-0.5x
We isolate x by subtracting both sides by 5
3-2.5x=0.5x
add 2.5x to both sides
3=2x
divide both sides by 2
x=2/3min
