Solve the system of linear equations using matrices.

-x = 2 + 5y + 5z
-5y + 4z = 19 - 4x
x + 5y - z = -20

Rewrite each equation in form ax+by+cz=d

x +
y +
z=

x +
y +
z=

x +
y +
z=

Use your calculator to find x, y and z

f . i can go whenever i feel like it bc it is confidential meaning only i would know how much i deposited besides the bank and they wouldnt care bc when you make a deposit you are using their services which means they are using there competition and gaining more customers

and if they dont well then thats less customers for them in a less profitable way

plz mark brainliest

y=20x

: )

hope this

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
