Solving for y. - y = -2x -5

Effectus [21]

Answer:

y = 2x+5

Step-by-step explanation:

Add y on both sides, this cancels out the y on the left side

add 2x and add 5 on both sides, this cancels out the -2x and the -5 on the left side.

Divide/Multiply both sides by -1, as it will cancel out the negatives as two negatives make a positive.

If you needed a value for y, more info is needed.

hope this helps (:

In 2009, the national debt of a government was about $10.5 trillion. Using 308.0 million as the population for that year, abo

Katarina [22]

Answer:

34091 dollars per person

Step-by-step explanation:

In order to answer the question, you have to divide the amount of debt by the amount of population to obtain the amount of dollars per person.

The debt was $10.5 trillion. A trillion is a thousand billion (1000 multiplied by a billion which is $10^{9}$ in scientific notation)

1000= $10^{3}$

One trillion is $(10^{3})(10^{9})=10^{12}$

The debt is: $ 10.5 x $10^{12}$

The population is scientific notation is: 308.0 x $10^{6}$

Dividing the amount of debt by the amount of population:

$\frac{(10.5)(10^{12})}{(308.0)(10^{6})}=\frac{(10.5)(10^{12-6})}{308.0}=\frac{(10.5)(10^{6})}{308.0}$

Simplifying and expressing it in standard notation:

34090.9 dollars per person

Rounding to the nearest dollar:

34091 dollars per person.
