According to the United States Census Bureau, on September 1, 2014, the population of the United States was increasing by 1 person every 12 seconds. At this rate, by how much would the
population of the United States increase in 1 year?

2,628,000 people per year.

Step-by-step explanation:

1 person every 12 seconds. There are 60 seconds in 1 minute. So, there are 60 / 12 = 5 people every minute.

There are 60 minutes in an hour. 5 * 60 = 300 people per hour.

There are 24 hours in a day. 24 * 300 = 7,200 people per day.

There are 365 days per year. 7,200 * 365 = 2,628,000 people per year.

Hope this helps!

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2
