Chapter 2.6, Problem 100E

(a)

To determine

To Calculate: The slope of the function $f\left(x\right)=-0.44x+13.62$ and its mean where the store’s two branches which are modeled by the functions:

$\begin{array}{l}f\left(x\right)=-0.44x+13.62\\ g\left(x\right)=0.51x+11.14\end{array}$

As $f$ and $g$ represent the profit in millions of dollars

(b)

To determine

To calculate: The slope of $g\left(x\right)=0.51x+11.14$ and its meanwhere the store’s two branches which are modeled by the functions:

$\begin{array}{l}f\left(x\right)=-0.44x+13.62\\ g\left(x\right)=0.51x+11.14\end{array}$

As $f$ and $g$ represent the profit in millions of dollars

(c)

To determine

To calculate: The value of $f+g$ and slope of this function and its mean $f\left(x\right)=-0.44x+13.62$ and $g\left(x\right)=0.51x+11.14$ where the store’s two branches which are modeled by the functions:

$\begin{array}{l}f\left(x\right)=-0.44x+13.62\\ g\left(x\right)=0.51x+11.14\end{array}$

As $f$ and $g$ represent the profit in millions of dollars
