Answer:

Gah! Inverses!

Step-by-step explanation:

This is a pretty simple concept, just switch the x and f(x) values!

If you don't understand, look at how I solve it!

$f(x)=\frac{1}{3} -\frac{1}{21} x$

Switching the positions of the x and f(x) values...

$x=\frac{1}{3} -\frac{1}{21} f(x)^{-1}\\$

Note: That f(x)^-1 is the proper notation for inverse functions.

$x-\frac{1}{3} =-\frac{1}{21} f(x)^{-1} \\f(x)^{-1}=-21x+7$

There you go!

Hope this helps, and don't procrastinate!

The area of a triangle is 84.335 in2. The height of the triangle is 8.35 in. To the nearest inch, what is the length of the base

Dmitry_Shevchenko [17]

The formula to find the area of a triangle is:
A = 1/2bh
84.335 = 1/2 b(8.35)
168.67 = 8.35b
20.2 = b.

84.335 = 1/2 (8.35)(20.2)
84.335 = 1/2(168.67)
84.335 = 84.335

The base is 20.2 in.

Hope this helps =)
