Answer:
Option D ![F(x)=150(0.85)^{x}](https://tex.z-dn.net/?f=F%28x%29%3D150%280.85%29%5E%7Bx%7D)
Step-by-step explanation:
In this problem we have a exponential function of the form
![F(x)=a(b)^{x}](https://tex.z-dn.net/?f=F%28x%29%3Da%28b%29%5E%7Bx%7D)
where
F(x) -----> the rabbit population
x ----> the number of weeks
a is the initial value
b is the base
In this problem we have
a=150 rabbits
b=1-r
r=15%=15/100=0.15
so
b=1-0.15=0.85
substitute the values
![F(x)=150(0.85)^{x}](https://tex.z-dn.net/?f=F%28x%29%3D150%280.85%29%5E%7Bx%7D)
Answer:
1,-2
Step-by-step explanation:
You can also say the answer is C.
I set it up as a ratio with hours on the top and the fraction of the job on the bottom. It looks like this: 5/(2/3) / x/1, because 1 is the whole job if 2/3 is only a fraction of it. Cross multiplying gives you 2/3x = 5. Solving for x gives you that it will take 7.5 hours to complete a whole job if it takes 5 hours to complete 2/3 of it.
The last option because he spent $135 or more
Answer:
-3x + 9
Explanation:
Because these two integers that is - and - is said to be added and write the sign of of greater or bigger number.
