29.) KOI POND You are constructing a fountain in a triangular koi pond. You want the fountain to be

the same distance from each edge of the pond.

Where should you build the fountain? Explain your

reasoning. Use a sketch to support your answer.

answer: x=60

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
