The function f(x) varies inversely with x and f(x) = 6 when x = 4. what is f(x) when x = 8? a.24 b.3 c.12 d.10

3

Step-by-step explanation:

given f(x) varies inversely with x then the equation connecting them is

f(x) = ← k is the constant of variation

to find k use the given condition f(x) = 6 when x = 4, then

k = xf(x) = 4 × 6 = 24, hence

f(x) = ← variation equation

when x = 8, then

f(x) = = 3

the 3rd option is right

step-by-step explanation:

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
