Answer:
Hi thats the answer.
Step-by-step explanation:
Answer:
See answers to parts a and b below.
Step-by-step explanation:
A. Value: y=20+.20x
Best Rent y=30+.10x
B. 20+.20x=30+.10x make equations equal each other by subbing y values.
.10x=10 simplify equation
x=100
check answers by subbing 100 for x in each equation.
y=20+.20(100)
y=20+20
y=40
y=30+.10(100)
y=30+10
y=40
Both equations equal 40, so 100 is the correct number of miles for when Value equals Best Rent.

Answer:
The condensed log equation is: ![\log{\frac{x^4y}{z^5}}](https://tex.z-dn.net/?f=%5Clog%7B%5Cfrac%7Bx%5E4y%7D%7Bz%5E5%7D%7D)
Step-by-step explanation:
We use these following logarithm properties to solve this question:
![a\log{x} = \log{x^a}](https://tex.z-dn.net/?f=a%5Clog%7Bx%7D%20%3D%20%5Clog%7Bx%5Ea%7D)
![\log{a} + \log{b} = \log{ab}](https://tex.z-dn.net/?f=%5Clog%7Ba%7D%20%2B%20%5Clog%7Bb%7D%20%3D%20%5Clog%7Bab%7D)
![\log{a} - \log{b} = \log{\frac{a}{b}}](https://tex.z-dn.net/?f=%5Clog%7Ba%7D%20-%20%5Clog%7Bb%7D%20%3D%20%5Clog%7B%5Cfrac%7Ba%7D%7Bb%7D%7D)
In this question:
![4\log{x} = \log{x^4}](https://tex.z-dn.net/?f=4%5Clog%7Bx%7D%20%3D%20%5Clog%7Bx%5E4%7D)
![5\log{5} = \log{z^5}](https://tex.z-dn.net/?f=5%5Clog%7B5%7D%20%3D%20%5Clog%7Bz%5E5%7D)
So
![4\log{x} + \log{y} - 5\log{z}](https://tex.z-dn.net/?f=4%5Clog%7Bx%7D%20%2B%20%5Clog%7By%7D%20-%205%5Clog%7Bz%7D)
Becomes:
![\log{x^4} + \log{y} - \log{z^5}](https://tex.z-dn.net/?f=%5Clog%7Bx%5E4%7D%20%2B%20%5Clog%7By%7D%20-%20%5Clog%7Bz%5E5%7D)
Now applying the addition and subtraction properties, we have:
![\log{\frac{x^4y}{z^5}}](https://tex.z-dn.net/?f=%5Clog%7B%5Cfrac%7Bx%5E4y%7D%7Bz%5E5%7D%7D)
The condensed log equation is: ![\log{\frac{x^4y}{z^5}}](https://tex.z-dn.net/?f=%5Clog%7B%5Cfrac%7Bx%5E4y%7D%7Bz%5E5%7D%7D)
