The answer is the option D.

You have to use implicit derivative

1) dy / dx = y'

2)

$xy^3+y=3x

y^3+3xy^2y'+y'=3

(3xy^2+1)y'=3-y^3

y'= (3-y^3)/(3xy^2+1)

y'=(3-y^3)/(1+3xy^2)

Solve the proportion for X. 5/2.5= X/2 1 4 5.5 6.25

Sav [38]

Answer:

$\large \boxed{X = 4}$

Step-by-step explanation:

5/2.5 = X/2

To solve a proportion, use the following equation:

(numerator * opposite denominator) = (numerator * opposite denominator)

Substitute in given numbers

(5 * 2) = (X * 2.5)

Multiply to simplify

10 = 2.5X

Divide both sides of this equation by 2.5

$\large \boxed{X = 4}$

Hope this helps :)
