Question

For the equation given below, evaluate y' at the point (−12).
5xy−4x+6=0

Answer 1

implicit differentiation

Answer 2

yeah i tried it and i get 5dy/dx =4 and i know i am suppose to divide by 5 but then i dont know where to plug in my point (-1,2)

Answer 3

\[5xy'+5y-4=0\]

Answer 4

you solve 5xy as a product

Answer 5

oh so im suppose to do the product rule

Answer 6

any time you differentiate x then y is like a constant

Answer 7

when you differentiate y then x is like a constant followed by y'

Answer 8

okay thank you

Answer 9

my answer is different from yours

Answer 10

absolutely\[Vdu+Udv\]

Answer 11

NOW YOU PUT YOUR VALUES

Answer 12

okay do you think you can check my answer i think i need to do it again

Answer 13

\[5(-1)y'+5(2)-4=0\]

Answer 14

BODMAS is important here

Answer 15

\[-5y'+10-4=0\]

Answer 16

so my final answer was 6/5 is that correct

Answer 17

\[y'=\frac{ 6 }{ 5}\]

Answer 18

yw

Answer 19

thanks
