Step-by-step explanation:

Answer:
Option c.
Step-by-step explanation:
It is given that the piecewise function represents the Social Security taxes for 2009.

We need to find Rachel's security tax if she earned $102,000 in 2009.
Since 102,000 lies in
, therefore

Put x=102000.


So, the Social Security tax is $6324.
Therefore, the correct option is c.
Answer:
f(19)=3/21-4=-3.857
Step-by-step explanation:
f(x)=3/(x+2)-sqrt(x-3)
f(19)=3/(19+2)-sqrt(19-3)
f(19)=3/21-sqrt(16)
f(19)=3/21-4
f(19)=-3.857
The associative property of addition is shown in equations where the order in which the evaluation is made does not change the result, providing the numbers remain in the same order. Option B demonstrates this.
12/7 + 8/7
12+8 = 20
20/7 = 2 and 6/7ths
