Two cars leave the same parking lot, with one heading south and the other heading east. After several minutes, the southbound car has traveled 15 miles, and the eastbound car has traveled 20 miles. Measured in a straight line, how far apart are the two cars?

answer is b

step-by-step explanation:

y/x of point b= y/x of point a

step-by-step explanation:

(i got the same question, this was the correct answer.)

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)
