Answer:
5.75 days
Step-by-step explanation:
Given data
let the number of days be x and the number and the number of miles be y
so that the cost of the rental will be
c= 38.38x+ 0.14y---------1
we are told that the amount at hand is $270
hence
270=38.38x+ 0.14*(350)
solve for x
270= 38.38x+49
270-49= 38.38x
221= 38.38x
divide both sides by 38.38
x= 221/38.38
x= 5.75 days
Hence the number of days is 5.75 days
Answer:
5.18÷5=1.036 so round up to 1.04

Solving for the input,
, given the output:
Given:
![f(x) = 4x -4](https://tex.z-dn.net/?f=f%28x%29%20%3D%204x%20-4)
Solving for
from the equation,
:
![f(x) = 0 \\ 4x -4 = 0 \\ 4x = 4 \\ x = \frac{4}{4} \\ x = 1](https://tex.z-dn.net/?f=f%28x%29%20%3D%200%20%5C%5C%204x%20-4%20%3D%200%20%5C%5C%204x%20%3D%204%20%5C%5C%20x%20%3D%20%5Cfrac%7B4%7D%7B4%7D%20%5C%5C%20x%20%3D%201)
Solving for the output,

Given:
![f(x) = 4x^2 -4x](https://tex.z-dn.net/?f=f%28x%29%20%3D%204x%5E2%20-4x)
Solving
:
![f(-7) = 4(-7)^2 -4(-7) \\ f(-7) = 4(49) -4(-7) \\ f(-7) = 196 +28 \\ f(-7) = 224](https://tex.z-dn.net/?f=f%28-7%29%20%3D%204%28-7%29%5E2%20-4%28-7%29%20%5C%5C%20f%28-7%29%20%3D%204%2849%29%20-4%28-7%29%20%5C%5C%20f%28-7%29%20%3D%20196%20%2B28%20%5C%5C%20f%28-7%29%20%3D%20224)
