Answer:

Step-by-step explanation:

f(x) = \frac{4}{x}\\\\f(a) = \frac{4}{a}\\\\f(a+h) = \frac{4}{a+h}\\\\\frac{f(a+h) - f(a)}{h} = \frac{\frac{4}{a+h} - \frac{4}{a}}{h}

                =\frac{\frac{4(a)}{(a+h)a} - \frac{4(a+h)}{a(a+h)}}{h}\\\\=\frac{\frac{4a - 4a - 4h}{a(a+h)}}{h}\\\\=\frac{\frac{ - 4h}{a(a+h)}}{h}\\\\= \frac{-4h}{a(a+h) \times h}\\\\= -\frac{4}{a(a+h)}\\\\

Generally  comparable starting salary C is given as

   C=\frac{starting salary}{CPI for 2013(index} *CPI for 2003(index)

   C=\frac{34,862}{232.957} *184

Free_Kalibri [48]

\bf Step-by-step~explanation:

Keep in mind: The entire line segment (VX) is equal to 14.

\bf Step~1:

Let's see how the line segment looks like first.

Line segment VX is 14 units long.

             14

______________

V                         X

W is on the line segment somewhere, and VW is equal to 3.

     3              ?

______________

V           W           X

\bf Step~2:

We have to solve for the <em>?.</em> Let's put ? as x. So now we are solving for x.

We have to set up our equation like this:

x + 3 = 14

Since our unknown value plus 3 is equal to 14, we have to subtract 3 from 14 to get our answer.

14 - 3 = 11

   3               11

______________

V           W           X
