Note that if

, then

, and so we can collapse the system of ODEs into a linear ODE:


which is a pretty standard linear ODE with constant coefficients. We have characteristic equation

so that the characteristic solution is

Now let's suppose the particular solution is

. Then

and so

Thus the general solution for

is

and you can find the solution

by simply differentiating

.
(4.5,6) that is what i got.
slope intercept form equation, y = mx + b
answer, y = -2x + 4
Answer:
40%
Step-by-step explanation:
sloution is 16/40 only this we can get answer
<span>240 <= 171 + x <= 270
and now subtract 171 from all and get
69 <= x <= 99
So any score from 69 to 99 will do.</span>
