Answer: D) 
Step-by-step explanation:
From the given table we can see that this is not representing a linear function as the rate of change is not constant.
So it can be exponential growth function
, where A is the initial amount , b is the multiplicative rate of growth and n is the time period in weeks.
Now here at n=1 , f(n)=8
Therefore, A=8
Now, for n=2

By substitute the values of A and b in the above equation, we get the equation 
Therefore, the function best shows the relationship between n and f(n) is
, where n is the number of weeks.
C. As the inequality is less than therefore x can be any number below 250, but cannot include 250 therefore must be fewer
Answer:
option 2: y - 5x + 3
Step-by-step explanation:
you would first distribute the 10 and then divide the entire left side by 2
