Using the concept of y-intercept, it is found that the response that is not correct is given by:
B) Replace x with -x.
<h3>What is the y-intercept of a function?</h3>It is the value of the function when x = 0, hence it is the point (0, f(0)).
In this problem, the function is:
The y-intercept is given by:
If we just replace x with -x, we still have the same expression as above, hence the y-intercept does not change and option B is the answer to this question.

Answer:
Ratio of blue fish in the small tank to the red fish in large tank is 10 : 6279
Step-by-step explanation:
Let the number of red fish and blue fish in the large tank are x and y respectively.
Similarly ratio of red fish and blue fish in the small tank are x' and y' respectively.
Since in each tank ratio of the red fish to blue fish is 333 : 444
That means x : y = 333 : 444
Or
⇒
⇒ y = --------(1)
Similarly x' : y' = 333 : 444
⇒
⇒
⇒ x' = ------(2)
Ratio of the fish in large tank to the fish in small tank is 464646 : 555
So (x + y) : (x' + y') = 464646 : 555
Now we replace the values of x and y' from equation (1) and equation (2)
Therefore, ratio of blue fish in the small tank to the red fish in large tank is 10 : 6279
