Answer:

Step-by-step explanation:
you have the matrix
![A=\left[\begin{array}{cc}0&-1\\-1&0\end{array}\right]](https://tex.z-dn.net/?f=A%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D0%26-1%5C%5C-1%260%5Cend%7Barray%7D%5Cright%5D)
to find the eigenvalues it is necessary to solve the determinant

thus, we have the polynomial and the eigenvalues

and the eigenvectors

Hope this helps!

Answer:
56n - 35
Step-by-step explanation:
6n + 5(10n - 7) ← multiply each term in the parenthesis by 5

= 56n - 35
If M is a midpoint of PQ, then we can use the formula of a midpoint:

We have the endpoints (-2a, 0) and (0, 2b). Substitute:

<h3>Answer: M(-a, b)</h3>
