At a pond there were 24 ducks swimming. the ratio of ducklings to adult ducks is 5: 1. how many ducklings were swimming at the pond?

Step-by-step explanation:

Let

x------> the number of ducklings

y------> the number of adult ducks

we know that

------> equation A

so

------> equation B

Substitute equation B in equation A

clock

step-by-step explanation:

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
