If CJ=y+9 and JX=4y then y =3
Answer:
1% given away means 1/100 × 3= 0.03
therfore what is left is : 3-0.03= 0.97
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:
M is negative
Step-by-step explanation:
7 days a week
