Answer:
just took on edg2020 , option B is correct
Step-by-step explanation:
We can explicitly find the inverse. If is the inverse of , then
Solve for the inverse :
Then when x = -6, we have
Alternatively, we can first solve for x such that . Then taking the inverse of both sides, . (The difference in this method is that we don't compute the inverse for all x.)
We have
Conflict, she would be late to the interview which would cause some distress in the situation, thus being conflict.
I'm going to assume that "−" is supposed to be some kind of minus character, so that the given system of DEs is supposed to be
Take the Laplace transform of both sides of both equations. Recall the transform for a second-order derivative,
where <em>F(s)</em> denotes the transform of <em>f(t)</em>. You end up with
and solving for <em>X(s)</em> and <em>Y(s)</em> (nothing tricky here, just two linear equations) gives
Now solve for <em>x(t)</em> and <em>y(t)</em> by computing the inverse transforms. To start, split up both <em>X(s)</em> and <em>Y(s)</em> into partial fractions.
• Solving for <em>x(t)</em> :
Taking the inverse transform, you get
• Solving for <em>y(t)</em> :
Inverse transform:
10x+200 ;
X being how many oil changes she does (the unknown)
The slope should be up 10/1
