Two step equations Sally sold half of her comic books and then bought eight more. She now has twelve. How many did she begin with?

8

Step-by-step explanation:

Since she now has 12, subtract 8 because of the 8 she before added.

Now, you're left with 4.

The 4 is half of what she originally had, leading up to the fact that the answer is 8.

Sally began with eight comic books.

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.
