Answer:
From scatter plot companies can predict future sales, and what will happen next. To help with this predictions most companies draw a line through the scattered plot called best-fit line. This line should be close to most of the points on the scattered line. Approximately half the point on the top of the line and half on the bottom.In this case the company will ignore the points tat far away from the line.
As points, x-intercepts take the form
![(x,0)](https://tex.z-dn.net/?f=%28x%2C0%29)
, so to find the intercepts we can set
![y=0](https://tex.z-dn.net/?f=y%3D0)
and solve for
![x](https://tex.z-dn.net/?f=x)
.
![x\ln(x+e)=0\implies\begin{cases}x=0\\\ln(x+e)=0\end{cases}](https://tex.z-dn.net/?f=x%5Cln%28x%2Be%29%3D0%5Cimplies%5Cbegin%7Bcases%7Dx%3D0%5C%5C%5Cln%28x%2Be%29%3D0%5Cend%7Bcases%7D)
From the first equation alone, we already know that
![x=0](https://tex.z-dn.net/?f=x%3D0)
is a solution, which means one intercept is
![(0,0)](https://tex.z-dn.net/?f=%280%2C0%29)
.
The second equation gives
![\ln(x+e)=0\implies e^{\ln(x+e)}=e^0\implies x+e=1\implies x=1-e](https://tex.z-dn.net/?f=%5Cln%28x%2Be%29%3D0%5Cimplies%20e%5E%7B%5Cln%28x%2Be%29%7D%3De%5E0%5Cimplies%20x%2Be%3D1%5Cimplies%20x%3D1-e)
so that the second intercept occurs at
![(1-e,0)](https://tex.z-dn.net/?f=%281-e%2C0%29)
.
So if
![a=0](https://tex.z-dn.net/?f=a%3D0)
and
![b=1-e](https://tex.z-dn.net/?f=b%3D1-e)
, we have
![a+b=1-e](https://tex.z-dn.net/?f=a%2Bb%3D1-e)
, giving C as the answer.
Answer:
g-1(4)=-5
Step-by-step explanation:
because inverse mean that you will switch every x and y on the original graph
for example; point( 4,-2) inverse will be (-2,4)
so to find x=4 on the inverse than just find y=4 on the origin graph
So, ($299.95)(. 30) = $89.99
$299.95 - $89.99= $209.96
($209.96)(.05)=$10.50
$209.96 + $10.50 = $220.46
