We're going to be on the decimal graph and calculator online, and we're going to put in the equation 20 minus the square root, which you will find if you open the keypad, the square root of 5x plus 5, and hit enter in another line, put y equals 14 minus 0 .1 .1x.
00:23
If you're using handheld, go to your y equals, put one of the equations in y1 and the other in y2, and then use the zoom button to try to find where you can see both intersections.
00:34
For the desmos, you can zoom in and out here, or if you have a mouse or a trackhead where you can zoom in and out, you can use that feature too.
00:46
And so we have to zoom out quite a bit in order to see these two intersections.
00:53
To clean it up, i might say, well, i want my x's to go maybe from negative 20 to 500.
01:09
And maybe i go, i won't choose a step.
01:13
And for the ys, it doesn't look like, you know, we need to go down very far.
01:19
So maybe from negative 50 to positive 40.

This is one of many windows that will work...
