WebWe choose the row for which x 5 is the label as the pivot row, and refer to x 5 as the leavingvariable—the one that changes from being basic to being nonbasic. The pivot row selection process just outlined is called the ratio test. By setting λ = 1, we have that x 1 and x 5 are zero, while the other variables remain nonnegative. WebIs he here? Yeah. Normally, we would choose the most negative. But, you see, we would have to abandon all coms. We shouldn't have a negative denominator. And so we kind of have for going to proceed so we could try that. So smallest ratio, this one's 25. This one. Let's change the on. Let's want his ear out.
