- Traffic flow. In the analysis of traffic flow, a certain city estimates the following situation for the "square" of its downtown district. In the following figure, the arrows indicate the flow of traffic. If x₁ represents the number of cars traveling between intersections A and B, x2 represents the number of cars traveling between B and C, x3 the number between C and D, and x4 the number between D and A, we can formulate equations based on the principle that the number of vehicles entering an intersection equals the number leaving it. That is, for intersection A we obtain 200+x4 = 100+x₁ Formulate equations for the traffic at B, C, and D. Solve the system of these four equations.

- Find all solutions of the system of equations.arrow_forwardYour discussion response for this unit will consist of two parts. First, create 3 equations of the form , where a, b, c, and d are constants (integers between – 5 and 5). For example, . Perform row operations on your system to obtain a row-echelon form and the solution. Go to the 3D calculator website GeoGebra: www.geogebra.org/3d?lang=pt and enter each of the equations. After you have completed this first task, choose one of the following to complete your discussion post. 1. Reflect on what the graphs are suggesting for one equation, two equations, and three equations, and describe your observations. Think about the equation as a function of x and y, for example, in the example above. Geogebra automatically interprets this way, that is, like , it isolates z in the equation. 2. What did the graphs show when you entered the second equation? 3. Give a simple description of the system x=0y=0z=0 x = 0 can be seen as the constant function . Of course, you can use GeoGebra to “observe”…arrow_forwardsolve without math labarrow_forward
