If x is a number that is 7 more than y, how do you express x as a function of y?

1 answer:

8 0

I believe the correct answer from the choices listed above is option B. The variable y is the independent variable here and x is the dependent variable so the function can be represented as f(y). The function should be written as:

<span>x = f(y) = 7 + y</span>

Answer:

S = v1 t1 = 7 t1 traveling downstream

S = v2 t2 = 5 t2 traveling upstream

7 t1 = 5 t2

7 (6 - t2) = 5 t2 since t1 + t2 = 6

42 - 7 t2 = 5 t2

t2 = 42 / 12 = 3.5 hrs so t1 = 2.5 hrs

S = 7 t1 = 7 * 2.5 = 17.5 mi

Also, S = 5 t2 = 5 * 3.5 = 17.5 mi
