Independent-a variable (often denoted by x) whose variation does not depend on that of another

dependant-a variable (often denoted by y) whose value depends on that of another.

4 stays the same but just add 5 and 3 and answer is B

Let . Then

and substituting these into the ODE gives

Let , so that . Then the ODE is linear in , with

Multiply both sides by , so that the left side can be condensed as the derivative of a product:

Integrating both sides and solving for gives

Integrate again to solve for :

and finally, solve for by multiplying both sides by :

already accounts for the term in this solution, so the other independent solution is .

**Answer:**

2nd one is the right answer.

**Answer:**

$13

**Step-by-step explanation:**

multiply 65 by 80 then divide by 100, you get 52, so subtract 65 from 52 you get 13
