The gross federal debt y​ (in trillions of​ dollars) for a certain country in year x is approximated by the following​ equation,
miskamm [114]

Answer: 2008

Step-by-step explanation:

Given : The gross federal debt y​ (in trillions of​ dollars) for a certain country in year x is approximated by the equation y =1.18x +1.58 , where x is the number of years after 2000.

To find the year in which the federal debt will be $10.68 trillion, we substitute y= 10.68 in the above equation , we get

10.68 =1.18x +1.58\\\\\Rightarrow\ 1.18x=10.68-1.58\\\\\Rightarrow\ 1.18x =9.1\\\\\Rightarrow\ x=\dfrac{9.1}{1.18}=7.7118644067\approx8

The required year will be = 2000+8=2008.

Hence, in 2008  the federal debt will be $10.68 trillion.

Rewrite equation to solve for m 4n-6m=-2
hram777 [196]

Answer:

Step-by-step explanation:

4n - 6m = - 2              Subtract 4n from both sides.

4n-4n - 6m = -2-4n

-6m = - 2 - 4n             Divide by - 6

-6m/-6= -2/-6 -4n/-6  Do the division

m = 1/3 + 2n/3

The signs change because each term has 2 minus signs. 2 minus signs make a plus. Or both minus signs cancel.
