Answer:

k = -13

Step-by-step explanation:

-4(k +2) = -k +31

you multiply the bracket by -4

-4k-8 = -k+31

Collect the like terms

-4k+k = 31+8

-3k =39

divide both sides by -3

k = -13

Answer:

k = -13

Step-by-step explanation:

<u>Distributive property</u>

(-4 x k + -4 x 2)

-4k + -8 = -k + 31

<u>subtract 31 from both sides. </u>

-4k - 39 = -k

<u>add 4k to both sides</u>

-39 = 3k

<u>divide 3 from both sides</u>

-13 = k

Find a general solution of y" + 4y = 0.
klio [65]

Answer:

y(x)=C_{1}cos2x+C_{2}sin(2x)

Step-by-step explanation:

It is a linear homogeneous differential equation with constant coefficients:

y" + 4y = 0

Its characteristic equation:

r^2+4=0

r1=2i

r2=-2i

We use these roots in order to find the general solution:

y(x)=C_{1}cos2x+C_{2}sin(2x)
