I don't know what your looking for, so be more specific, but I'm assuming your solving for x, so that's would be
x = -1
Yes, the inverse of a symmetric matrix is also symmetric.
Take the symmetric matrix A, we have:

and

This gives:

Using the properties:

and

We get:

Since

, we can perform the substitution to get:

Multiplying by

on both sides:



Proving that the inverse of a symmetric matrix is also symmetric.
Answer:
4 5/6 feet.
Step-by-step explanation:
The least common multiple for 2 and 3 is 6, so if we change the denominators to 6, we get Chrystelle's height as 3 3/6, and her mother is 1 4/6 ft taller than her.
3 3/6 + 1 4/6= ?
(Written as an Improper fraction)
21/6 + 10/6 = 31/6
31/6 = 4 5/6.

Answer:
A
Step-by-step explanation:
To find your answer, divide the price of the ink by how many pages it will print. In this case, option A gives you the best value at $0.08 per page.
Then y = -84
