The coordinate plane is being used in a number of different ways.
It is used on maps to define longitude and latitude. This allows you to define any point on the map using two unique numbers. This is very important in navigation and it made navigation simpler.
It is also used to graph functions. This way we can understand them better, and easier. These are just a couple of implications.
Coordinate plane introduced by Descartes seems like something we take for granted today, but without it, the world would be a very different place.
Multiply 5.8 x 107km then multiply 1.5 x 107 5.8x107=620.6 1.5x107=160.5 subtract those 620.6-160.5= eh its a
5/6 = 11/6 8/10 x 6/11 48/110 = 24/55 is the answer you can flip the 2nd rational and the sign can be changed to multiplication.
