Answer:
f(1/3) = 9
Step-by-step explanation:
f(x)=1/x+2/x
Combine terms
f(x) = 3/x
f(1/3) = 3 / (1/3)
f(1/3) = 9
3*60 = 180 minutes
80/180 = 0.44
1-0.44 = 0.56
it was a 56% decrease in commute time
Answer: ![d(x)=-750x^2-3750x-10500](https://tex.z-dn.net/?f=d%28x%29%3D-750x%5E2-3750x-10500)
Step-by-step explanation:
Given: The manager of a department store uses the given function to model the monthly opening inventory of down comforters at the store, in dollars, where x represents the number of months from September.
![d(x)=-750(x^2-5x-14)](https://tex.z-dn.net/?f=d%28x%29%3D-750%28x%5E2-5x-14%29)
To rewrite this hat reveals the store's opening inventory of down comforters in the month of September, multiply -750 on the bracket, we get
![d(x)=-750x^2-3750x-10500](https://tex.z-dn.net/?f=d%28x%29%3D-750x%5E2-3750x-10500)
0.8 is greater than 0.08, the reason for that is that 0.8 is equal to 8/10=80/100 and 0.08 is equal to 8/100. As a percentage, 0.8 would be 80% and 0.08 would be equal to 8%.
