7.4 to 8.2

Lesson 7.4, p398, ex 3.

-       This is a classic math problem. Click on the link below to watch a video just like example 3 on p398. Our math book uses "A" for Airplane, but in the video the teacher chose "P" for Plane. Other than this minor difference it's the exact same problem.

-       Remember that the wind will affect the  total speed (or ground speed or still air speed – all of these mean the same thing) of the plane.

-       If Plane goes with the wind, then Total Speed = speed of Plane  + speed of the Wind.... that is:  S=  P + W

-       If Plane goes against the wind, then it will go slower, so Total Speed = speed of Plane – speed of Wind.... that is: S = P – W .

-       Check out the video. It's a little complicated but hang in there. You can do it!  http://www.youtube.com/watch?v=yla2bk7jB_A

Khan Academy exercises on graphing inequality,

these are kind of tricky  to do on the computer because you have to drag the points on the xy coordinate, but in the end the answer in the screen should look just like the one on your paper .. . https://www.khanacademy.org/math/algebra/linear-equations-and-inequalitie/graphing-linear-inequalities/e/graphing_inequalities
