D(1/x)/dx= d(x^-1)/dx
= -x^-2
the derivatives of the two cases you mentioned is as follows:
(I) f(x)=k/x
d{f(x)}/dx= k×(-x^-2)
= -kx^-2
(ll) f(x)=x/k
d{f(x)}= d(x/k)/dx
= 1/k
you can just simply take out the constant from the derivative and multiply it to the final answer of the derivative of the given function.

Answer:
the first choice
Step-by-step explanation:
-0.8 is the smallest number considering it is negative.
-1/3 is negative too, but it is not as much at -0.8 since when reduced to a decimal, it's would be -0.3334 (rounding up).
2/3 is not as much as 1 since it is not a whole number.
1 is the biggest number in the graph.
Answer:
1. Proportional
2. Not proportional
3. Proportional
Step-by-step explanation:
Mike's proportion
Michael gave $1.32 tip for an order that cost $8.80
$1.32÷$8.80=0.15
Given
1. $2.22 for $14.80
$2.22÷$14.80 =0.15
It is proportional to Mike's tip
2. $1.86 for $10.50
$1.86÷$10.50=0.1771
It I not proportional to Mike's tip
3. $0.78 for $5.20
$0.78÷$5.20=0.15
It is proportional to Mike's tip
Therefore,
1. Proportional
2. Not proportional
3. Proportional
