Question

Will give medal and fan!!!

Answer 1

If f(x) varies directly with x and f(x) = 24 when x = -4, then what is f(x) when x = 12?

Answer 4

first find the constant of variation by finding k
f(x)=kx
24=k(-4)

Answer 5

Let f(x) = y
y = k x
When y = 24 and x = -4, k = -6
f(x) = -6 x

Answer 6

so it's -6?

Answer 7

f(x)=kx, then k=24/-4=-6
then
f(x)=-6x=-6(12)=-72

Answer 8

well @robtobey gave you the direct variation equation
to asnwer your question you have to plug in 12 for x in f(x)=-6x

Answer 9

it is a simple quest. Ask harder plzzz :)

Answer 10

Write the inverse variation equation for the relationship:

y varies inversely with x and y = 4 when x = 2.

Answer 11

I have 10 more

Answer 12

Ok thx

Answer 13

x y = k
k = 8 when x = 2 and y = 4.
x y = 8
\[y=\frac{8}{x} \]
