6. based on data from the u.s. department of agriculture, the average number of acres per farm x years after 2000 can be approximated by the model below. (round answers to 2 decimal places.) a(x) = (2078x-94458)/(13x-2164)use the model to estimate the average number of acres per farm in 2005

40.05 acres

Step-by-step explanation:

Let x = number of acres per farm x years after 2000.

In the year 2005, x = 2005 - 2000 = 5.

To estimate the average number of acres per farm in 2005, we have to replace the value x = 5 in the expression of A(x).

A(5) = (2078 . 5 - 94458) / (13 . 5 - 2164)

A(5) = (10390 - 94458) / (65 - 2164)

A(5) = (-84068) / (-2099)

A(5) = 40.05

21.10=3.10+2x

x=9

Step-by-step explanation:

21.10 is y

21.10=3.10+2x

Subtract 3.10 from both sides

18=2x

Divide by 2 on both sides

9=x

x=9
