Answer:
x = 6
y = -4
Step-by-step explanation:
Plug y into the first equation.
5x - 7(-x+2) = 58
Then, solve for x.
Plug in x back to any one of the equations to find y.
Answer:
The expression is not completely factored.
Step-by-step explanation:
The expression of 
can be broken up into two binomials:
![[x - 2][x + 2]](https://tex.z-dn.net/?f=%5Bx%20-%202%5D%5Bx%20%2B%202%5D)
Together, you have this:
![3[x - 2][x + 2]](https://tex.z-dn.net/?f=3%5Bx%20-%202%5D%5Bx%20%2B%202%5D)
** There is alot of missing information to this question, but at least you know how to work this out.

Answer: Identify which of the following functions are eigenfunctions of the operator d/dx: (a) eikx, (b) cos kx, (c) k, (d) kx, (e) e−ax2
Step-by-step explanation: First, we going to apply the operator derivate to each item. Remember that a function f is an eigenfunction of D if it satisfies the equation
Df=λf, where λ is a scalar.
a) D(eikx)/dx= ik*eikx, then the function is a eigenfunction and the eingenvalue is ik.
b) D(cos kx)/dx= -ksen kx, then the funcion is not a eigenfunction.
c) D(k)/dx=0, then the funcion is not a eigenfunction.
d) D(kx)/dx=k, then the funcion is not a eigenfunction.
e) D(e-ax2)/dx= -2ax*e-ax2, then the function is a eigenfunction and the eingenvalue is -2ax
