Web(a)Determine whether or not xT = (0,4,0,2) is an optimal solution to the following linear program. maximize 9x 1 + 3x 2 + 5x 3 + 22x 4 subject to 2x 1 −x 2 + 2x 3 + 6x 4 ≤8, 5x 1 + 3x 2 + x 3 + 2x 4 ≤16, 4x 1 + x 2 −x 3 + 3x 4 ≤12, x 1,x 2,x 3,x 4 ≥0 Solution: To see if x is optimal, we try to find a feasible dual solutiony WebStep 1: Enter the linear equation you want to find the slope and y-intercept for into the editor. The slope and y-intercept calculator takes a linear equation and allows you to calculate the slope and y-intercept for the equation. The equation can be in any form as long as its linear and and you can find the slope and y-intercept. Step 2:

Solve the following pair of linear equations by the substitution …

WebMar 29, 2024 · Example 4 Check graphically, whether the pair of equations x + 3y = 6 and 2x – 3y= 12 is consistent. If so, solve them graphically. Let equations be x + 3y = 6 2x – 3y = 12 Let’s draw their graphs For Equation (1) x + 3y = 6 Putting x … Weby″ − y = 0. The equation’s solution is any function satisfying the equality y″ = y. Obviously y1 = e t is a solution, and so is any constant multiple of it, C1 e t. Not as obvious, but still easy to see, is that y 2 = e −t is another solution (and so is any function of the form C2 e −t). It can be easily verified that any function ...
