Iheard of 97 horses has 19 white and some black horses what is the ratio of black horses to all horses

the raito of 19 and 97 is 19.587628865979%

Step-by-step explanation:

78:97

Step-by-step explanation:

Because you would need to find the black horses to all horses ratio when you only have the number of all horses and white horses, you would subtract 19 white horses from all 97 horses to find the number of black horses. That being said, the answer would be 78 black horses to all 97 horses.

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.
