Answer:

1.  Consistent independent.

2.  Coincident

3.  Inconsistent.

Step-by-step explanation:

4x + y = 8

x +  3y = 8   Multiply this equation by -4:

-4x - 12y = -32

Adding this to the first equation:

-11y = -24 giving y = -24/-11 = 2.18

Substituting in the first second equation:

x + 3(2.18) = 8 giving x = 1.46.

So this system of equations has roots (1.46, 2.18)  and is consistent independent.

2.

-4x + 6y = -2

2x - 3y = 1   Multiply this by -2:

-4x + 6y = -2

So these 2 equations are the same and will give the same graph on the coordinate plane, and so has:

Infinite solutions  and is coincident.

3.

5x - 2y = 4

5x - 2y = 6

We can see immediately that this system of equations has NO Solutions.

If we subtract the 2 equations  we get:

0 = -2 which is of course, absurd.

Classification Inconsistent.

If you had a billion dollars and you spend one dollar every second how many years would it take you to spend it all
trapecia [35]

Answer: 31.71 years

Step-by-step explanation:

First, we need to find how many seconds are in a day.

There are 24 hours in a day, 60 minutes in an hour, and 60 seconds in a minute.

There are 3,600 seconds in an hour. How did we find this? 60 (min) x 60 (sec)

There are 86,400 seconds in a day. 24 (hr) x 3,600 (sec)

Now we need to find how many seconds are in a year.

There are 365 days in a year, we can multiply that by 86,400.

365 x 86,400 = 31,536,000

Whew! Now that we have that out the way, we can now divide $1 billion by 31,536,000 seconds.

1,000,000,000/31,536,000 = 31.71 (rounded to the nearest hundredth)

If you had a billion dollars, it will take 31.71 years to spend one dollar every second.
