All right.

In number 62, you are asked to find the answer to this system.
00:08
The equation for the first one is kind of like a circle, but it's kind of like a squared out circle or a rounded off square.
00:15
And it looks like this in green.
00:18
And the x, y equals one, that's a hyperbola.
00:22
But it's the hyperbola y is equal to one over x, which looks like this in the blue.
00:30
You have one branch that's in quadrant one and one branch in quadrant three, because you either need positive times positive to equal one or negative times negative to equal one.
00:42
You can't have a negative times a positive or a positive then's a negative.
00:49
The graphing utility i use cannot get an exact answer.
00:54
So the answers that are here may not be perfectly rounded to the nearest hundredth, but they are, very close.
01:03
They're definitely to the nearest tenth.
01:06
The hundredth might be off by one hundredth, either one way or the other.
01:10
So as you can see, i scrolled over where the intersection is here in quadrant one, and i found that one of the solutions was at 1 .55 approximately and 0 .645.
01:31
So i rounded that to 0 .65...
