6.1b + -8.1 + -1.6b + 2.7b

7.2b+−8.1

Step-by-step explanation:

6.1b−8.1−1.6b+2.7b

=6.1b+−8.1+−1.6b+2.7b

=6.1b−8.1−1.6b+2.7b

=(6.1b−1.6b+2.7b)+(−8.1)

=7.2b+−8.1

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.
