Find dy/dx by implicit differentiation xy=6

dy/dx = -y/x

Step-by-step explanation:

xy = 6

x * dy  + y * dx = 0

Subtract y dx from each side

x dy = - y dx

Divide each side by dx

x dy /dx = -y dx/dx

x dy/dx = -y

Divide by x

dy/dx = -y/x

Step-by-step explanation:

Apply the derivative operator d/dx to xy = 6.  xy is a product, so we must use the product rule as well as the chain rule.

dy/dx = -y/x

(d/dx)(xy = 6)   works out to x(dy/dx) + y(dx/dx) = 0, or just x(dy/dx) + y = 0.

Solving this for dy/dx, we get, first, x(dy/dx) = -y, and then

dy/dx = -y/x

me! what did you put for this question?

step-by-step explanation:

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
