3x2y=2;2xy=8 Simple and best practice solution for 3x2y=2;2xy=8 Check how easy it is, to solve this system of equations and learn it for the future Our solution is simple, and easy to understand, so don`t hesitate to use it as a solution of your homeworkThus, we have the following table for the equation 2x y 8 = 0 x 1 3 2 y 6 2 4 Now, plot the points P (1, 6) and Q (2, 4) The point B (3, 2) has already been plotted Join PQ and QB and extend it on both ways Thus, PB is the graph of 2x y 8 = 0 The two graph lines intersect at B (3, 2) ∴x = 3 and y = 2 5 Solve the system of2x y = 8 ii 3x y= 10 ;
In the equation above, y 2 y 1 = Δy, or vertical change, while x 2 x 1 = Δx, or horizontal change, as shown in the graph providedIt can also be seen that Δx and Δy are line segments that form a right triangle with hypotenuse d, with d being the distance between the points (x 1, y 1) and (x 2, y 2)Since Δx and Δy form a right triangle, it is possible to calculate d using theTo graph each line you need 2 points You chose the points aiming for easy calculations and a nice looking graph For easiest calculations, I would set x=0 and x=5 and solve for y (Zeros are usually good choices, and I picked x=5 because I saw it would give y values that would not be too large) For equation 3x y = 8 x=0 > y=8 (That Transcript Ex 63, 7 Solve the following system of inequalities graphically 2x y ≥ 8, x 2y ≥ 10 First we solve 2x y ≥ 8 Lets first draw graph of 2x y = 8 Putting x = 0 in (1) 2(0) y = 6 0 y = 6 y = 8 Putting y = 0 in (1) 2x (0) = 6 2x = 8 x = 8/2 x = 4 Points to be plotted are (0, 8), (4, 0) Drawing graph Checking for (0, 0) Putting x = 0, y = 0 2x y ≥ 8 0 ≥ 8 which
