00:01
All right, so the first one, we need to set all these equal to y equals first.
00:05
So, x plus 2y less than are equal to 24, subtract x on both sides.
00:13
So 2y less than are equal to negative x plus 24, divide by 2 all the way across.
00:21
So y is less than or equal to negative 1 half x plus 12.
00:28
All right, so let's graph it.
00:29
So we're going to start at 12, and then down one half, down one over two, down one.
00:49
All right, so here is our line, and it's less than.
01:00
So we're going to shade less than envelope.
01:04
It's less than or equal to, so it was a solid line.
01:07
All right, so the next one, x plus y, less than or equal to 15, subtract to x on both sides.
01:15
So y is less than or equal to negative x plus 15.
01:19
So we're going to start at 15.
01:24
And then go down 1 over 1, down 1 over 1.
01:37
So there's that line.
01:40
And it's also less than.
01:43
So we're going to shade below...
