Answer: She will need a minimum of 38 hours, at 38 hours she will make 456, plus the 300 she already has, so that in total is 756.
Step-by-step explanation:
750-300=450
450/12= 37.5
you can work for 37.5 hours so round to 38.

Answer:
The general solution of the system is
Step-by-step explanation:
To verify that the system ![X^{'} =\left[\begin{array}{cc}1&3\\3&1\end{array}\right] X](https://tex.z-dn.net/?f=X%5E%7B%27%7D%20%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D1%263%5C%5C3%261%5Cend%7Barray%7D%5Cright%5D%20X)
has the solutions given,
First, we determine the Eigen Values β of the matrix of the form 
Using |A-βI|=0, where I is the Identity Matrix, we have:
Subtracting matrices
Taking the determinant
We determine the eigen vector using
When 
= -2,
which implies that 
and thus
When = 4,
which implies that 
and thus
A general solution of the system is given as
where the c's are the eigen vectors.
Thus the general solution is
Answer:
c) does not make sense, y-int is (0,-8). a) the graph does show a linear line. b) sure it works, the x-int is 3. d) yes the line is infinite both ways (x,y) x (infinite, -infinite) y (infinite, - infinite)
Step-by-step explanation:
