Answer:
Average mean salary 
Step-by-step explanation:
We have been given year and respective salaries in each year.
1960 $4,995
1970 $8,626
1980 $15,970
1990 $31,367
2000 $41,807
2010 $55,202
Now we nee do to determine the average mean salary for the six decades, 1960 – 2010.
So we just need to add all those six salaries and divide that sum by 6 to find the average mean salary.
Average mean salary 
Average mean salary 
Average mean salary 
Hence final answer is approx:
Average mean salary 
Answer: z=83/c - 7 + t
Step-by-step explanation:
The function that would best represent the given condition above is,
f(x) = 24 / (3x - 2)
To determine the value of f(-2), substitute -2 to all the x's in the function such that,
f(-2) = 24 / ((3)(-2) - 2) = -3
The value of f(-2) is -3.
Answer:

Domain:

Step-by-step explanation:
we are given


Calculation of (f-g)(x):

we can plug it

now, we can simplify it



Domain:
we know that
domain is all possible values of x for which any function is defined
and f(x),g(x) and (f-g)(x) are polynomials
so, domain will be all real numbers
so, we get
