In order to find out where your holes and asymptotes are is to factor both the top and the bottom of that rational function. The numerator factors to (x+2)(x-2) and the denominator factors to x(x+1)(x-2). So since there is an (x-2) in both the numerator and denominator, that is called a removable discontinuity which we also know as a hole. The other factors in the denominator, the x and the (x+1) are vertical asymptotes, or values of x that make the rational function undefined (you're NEVER allowed to have a 0 in the denominator of a fraction!). So your correct choice is c. The way you find the y coordinate for the hole is to plug in 2 for x and solve it for y. No biggie.
Answer:
9 hours
Step-by-step explanation:
If she makes $ 20 for each car, washing 9 cars in 3 hours would get $ 180.
So she will need to work 9 hours 180 + 180 + 180, washing 9 cars in 3 hours and would get $ 540. This is enough to buy her phone and she will have a surplus of $ 120.
In summary she must work 9 hours

Answer:
the polygon on the right side is doubled the size of the one on the left, therefore x=11
Answer: No
Step-by-step explanation:
An event that cannot possibly happen has a probability of zero. If there is a chance that an event will happen, then its probability is between zero and 1. Thus, an unlikley event would be a low probability, not 0
