To find the inverse function, interchange the variables and solve for y.
f^-1(n) = 1/2 + n/3
Area = 10 * 1/2* * 14 * 25 (note decagon has 10 sides)
= 1750
ANSWER
See explanation
EXPLANATION
The table contains these two points (-4,-3) and (2,-4.5)
The slope of this line is given by;



The y-intercept can be obtained by finding the equation of the line in the form:

We plug in the slope and the point (-4,-3) to find c.
This implies that,



Hence the y-intercept is -4.
The given line is

This is already in the slope intercept form:
The slope is

The y-intercept is c=1
The answer is,

Also equivalent to about, 0.185188.
Answer: For the first on its a total of $5 dollars for the second one its a total of $3.45 cents
So all in total $8.45
