You can do:
6x7000 then
6x300 then
6x80 then
6x1 then
you add all the product.
the answer 4,4286
I believe the answer should be approximately 6,147 because you would plug into the equation y=20,000(.95)^t, where t=23.
Yes it is a polynomial .
The degree of polynomial is 4 and there is no power as a fraction or negative integer
SImple,
this line is in the form of y=mx+b..which means that m=slope and b=y-intercept..
Thus, the slope for this line is....

Thus, your answer, A.
