Question

calculate d/dx

Answer 1

Ok whats the equation

Answer 2

y=3x+9/8x-1

Answer 3

the derivative for those are 3 and 8 but what do I use to solve it? Product rule? Quotient rule?

Answer 4

You have to use the quotient rule

Answer 5

That would be the quotient rule

Answer 6

So \[\frac{ f'(x)g(x)-f(x)g'(x) }{ g(x)^2 }\]

Answer 7

ok so i got the answer 48x+69/128x-16 but my online hw is saying that it is incorrect

Answer 8

Well lets break it down further:

We know that d/dx is

\[\frac{ (3)(8x-1)-(3x+9)(8) }{ (8x-1)^2 }\]

So just simplify it:

\[\frac{ 24x-3-24x-72 }{ (8x-1)^2 }\]
Notice how I distributed the minus sign in -(24x-72)

Answer 9

Sorry on the last statement I ment distributin gthe minus sign -(24x +72)
