The function f is defined by f(x)=200÷x−b, where b is a constant. Find b, if the value of f at x= 1/3 is equal to 150.
Answers
Answer:
450
Step-by-step explanation:
f(x) = (200/x) -b
150 = (200/(1/3)) - b
150 = 600 -b
b = 450

" z + z + z " is just 3z and doesn't depend on 'x' or 'y'.
If z=-4, then (z + z + z) = 3z = -12.

We have no idea how 'x' responds to changes in 'y'.
We don't even know their units, to make a guess with.
-- If 'x' and 'y' are the ages of two people, then when y = 30, 'x' will be 23.
-- If they are the frequency and wavelength of a wave on the lake,
then when y = 30, 'x' will be 2 .
-- If 'x' is the weight of a rock in your front yard and 'y' is the number of pages
in today's newspaper, then 'y' has no effect on 'x'. No matter what happens
to 'y' . . . 'x' will always be 5 .
With the information given in the question, we just don't know.
We need either an equation, or else one more example.
