Answer: -10

Step-by-step explanation: For this problem we will solve the numbers in order.

-4 - 5 + 4 + (-5)

First subtract -4 - 5, which will give you -9. Then add -9 to 4, which will give you -5. Lastly add -5 plus -5, which will give you an answer of -10.

Consider the equation ay'' + by' + cy = d, where a, b, c, and d are constants. (a) find all equilibrium, or constant, solutions

Orlov [11]

Rewrite equation so that it is homogeneous .
$ay'' +by' + cy = 0$

Solve characteristic equation:
$ar^2 +br + c = 0 \\ \\ r = \frac{(-b) \pm \sqrt{b^2 -4ac}}{2a}$

The solutions to the homogeneous equation are:
$y = k_1 e^{r_1 t} + k_2 e^{r_2 t}$

Finally you need the constant term in "cy" to equal 'd' to satisfy the particular solution.
$y= k_1 e^{r_1 t} + k_2 e^{r_2 t} + \frac{d}{c}$
