dy/dx = 10exp(2x) - 4; when x = 0, y = 6. Find the value of y when x = 2.

First, we must evaluate what is given in the question. As it can be seen, the expression indicates that the problem consists of a first-order differential equation. We are also given the values of x and t...

Differentiate implicitly with respect to x the equation x^3*y^5+3x=8y^3+1

3x2y5+5x3y4y'+3 = 24y2y'

3x2y5+3 = (24y2–5x3y4)y'

y' = (3x2y5

Having x(x+4)=y, calculate dy/dx

Considering that x(x+4) = x^2+4x, and having that the derivative of the sum is the sum of the derivatives.

dx/dy x^2 = 2x and dx/dy 4x = 4 , then dx/dy x(x+4) = 2x+4
