C = 10m + 30, where C is total cost and m is # of months
C = 10(5) + 30
C = 50 + 30
C = $80
$160 = 10m + 30
160 - 30 = 10m
130/10 = m
m = 13 months
Hope that helps
Here is a method that makes it seem easier.
<span>Write down any number between 51 and 59. </span>
<span>For example you might choose 57 = 3*19 </span>
<span>Divide both numbers by 10 and write the answer as </span>
<span>0.3 * 1.9 = 0.57</span>

Answer:
Step-by-step explanation:
The given quadratic form is of the form
.
Where .Every quadratic form of this kind can be written as
Observe that is a symmetric matrix. So is orthogonally diagonalizable, that is to say, where is an orthogonal matrix and is a diagonal matrix.
In our case we have:
The eigenvalues of are .
Every symmetric matriz is orthogonally diagonalizable. Applying the process of diagonalization by an orthogonal matrix we have that:
Now, we have to do the change of variables to obtain
Which can be written as:
