Webf : R2 → R, f(x,y) = x−y, subject to the constraint x4 +y4 = 32. Also, at which points are these minimum and maximum values achieved? [15] (b) Dr Mistake wishes to find the maximum … WebWhich is the best approximation for the solution of the system of equations? y = -2/5x + 1. y = 3x - 2. (0.88, 0.65) Heather writes the equations below to represent two lines drawn on the coordinate plane. -6x + 18y = 0. 4x - 12y = 20. After applying the linear combination method, Heather arrived at the equation 0 = 60. Web3x + 2y = 11. Solution. Add the equations. x − 2y = 9 3x + 2y = 11 4x + 2y = 20. Isolate the variable in the new equation. 4x = 20 x = 5. Substitute x = 5 into either of the original equations to find y. x − 2y = 9 (5) − 2y = 9 . −2y = 4 y = −2. Identify the ordered pair that is the solution. A check in both equations will show that ... kachin alliance
