differential equations: solve the initial value problem
x2y' - xy = 2
y(1) = 1

Step-by-step explanation:

Divide both sides of the equation by :

Find the integrating factor:

Multiply the equation by the integrating factor:

The left side is the derivative of (xy), therefore we can write the equation as:

That is a separable equation. We separate and integrate:

We get:

Then plug the initial value y(1)=1, which means to plug x=1 and y=1:

Therefore, the solution once we plug C=1 becomes:

Then solving for y by dividing both sides by x, we get:

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

its c or d   take a lucky guess my dude
