Y 2 X 3 3Y. Transcript Ex 63 11 Solve the following system of inequalities graphically 2x + y ≥ 4 x + y ≤ 3 2x – 3y ≤ 6 First we solve 2x + y ≥ 4 Lets first draw graph of 2x + y = 4 Putting x = 0 in (1) 2(0) + y = 4 0 + y = 4 y = 4 Putting y = 0 in (1) 2x + (0) = 4 2x = 4 x = 4/2 x = 2 Points to be plotted are (0 4) (2 0) Drawing graph Checking for (00) Putting x = 0 y = 0 2x + y ≥.

The tangent line is parallel to the x axis when the slope (hence dy/dx) is zero and it is parallel to the y axis when the slope (again dy/dx) goes to oo or oo We’ll start by finding dy/dx x^2 + xy + y^2 = 7 d/dx(x^2 + xy + y^2) = d/dx(7) 2x + 1y +xdy/dx + 2y dy/dx = 0 dy/dx = (2x+y)/(x+2y) Now dy/dx = 0 when the nuimerator is 0 provided that this does not also make.
