Which of the following can not be used on a matrix when solving a system of equations?
a. interchange rows
b. multiply a row by a constant
c. add a constant to a row

c 1 hour

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.
