Answer:
if so 2130.12548...x^2
Step-by-step explanation:
Hey there!!
f(x) is basically ' y '
In order to inverse a equation, we will need to switch the values of x and y
The equation :
![y = 2x - 10](https://tex.z-dn.net/?f=y%20%3D%202x%20-%2010)
Now switching the positions :
![x = 2y - 10](https://tex.z-dn.net/?f=x%20%3D%202y%20-%2010)
![x + 10 = 2y](https://tex.z-dn.net/?f=x%20%2B%2010%20%3D%202y)
![y = \frac{x+10}{2}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7Bx%2B10%7D%7B2%7D)
![y = \frac{x}{2} + 5](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7Bx%7D%7B2%7D%20%2B%205)
This is the inverse.
Hope my answer helps!
Answer:

Step-by-step explanation:
We know that radius of a circle is perpendicular to the tangent of the circle at the point of contact.
![\therefore x\degree +90\degree +90\degree+124\degree =360\degree\\\therefore x\degree +304\degree =360\degree\\\therefore x\degree =360\degree-304\degree\\\huge\purple{\boxed{\therefore x\degree =56\degree}}](https://tex.z-dn.net/?f=%5Ctherefore%20x%5Cdegree%20%2B90%5Cdegree%20%2B90%5Cdegree%2B124%5Cdegree%20%3D360%5Cdegree%5C%5C%5Ctherefore%20x%5Cdegree%20%2B304%5Cdegree%20%3D360%5Cdegree%5C%5C%5Ctherefore%20x%5Cdegree%20%3D360%5Cdegree-304%5Cdegree%5C%5C%5Chuge%5Cpurple%7B%5Cboxed%7B%5Ctherefore%20x%5Cdegree%20%3D56%5Cdegree%7D%7D)
Answer:
A:
The decreasing value of car 1 can be represented by an exponential function and car 2 by a linear function
B:
Car 1: f(x) = ![18500(0.94)^{x}](https://tex.z-dn.net/?f=18500%280.94%29%5E%7Bx%7D)
Car 2: f(x) = 18500 - 1000x
C:
Car 1 would be $10600.40 after 9 years
Car 2 would be $9500.00 after 9 years
There is a significant difference of $1100.40 in value.
Step-by-step explanation:
![f(x) = ar^{x}\\f(0) = a = 18500\\f(x) = 18500r^{x}\\f(1) = 18500r = 17390\\r = \frac{17390}{18500} = 0.94\\f(x) = 18500(0.94)^{x}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20ar%5E%7Bx%7D%5C%5Cf%280%29%20%3D%20a%20%3D%2018500%5C%5Cf%28x%29%20%3D%2018500r%5E%7Bx%7D%5C%5Cf%281%29%20%3D%2018500r%20%3D%2017390%5C%5Cr%20%3D%20%5Cfrac%7B17390%7D%7B18500%7D%20%3D%200.94%5C%5Cf%28x%29%20%3D%2018500%280.94%29%5E%7Bx%7D)
