Answer:
(x, y, z) = (-3, -1, 3)
Step-by-step explanation:
Many graphing calculators can solve matrix equations handily. Here, we use a combination of methods.
Use the last equation to write an expression for z.
z = 4 -x +4y
Substitute this into the second equation:
y -4(4 -x +4y) = -13
y -16 +4x -16y = -13
4x -15y -3 = 0
In genera form, the first equation can be written as ...
3x +y +10 = 0
Now, the solution to these two equations can be found to be ...
x = (-15(10) -1(-3))/(4(1) -3(-15)) = (-150 +3)/(4+45) = -3 . . . using "Cramer's rule"
y = -(10 +3x) = -(10 -9) = -1 . . . . from the first equation
z = 4 -(-3) +4(-1) = 3 . . . . . . . . from our equation for z
The solution to the system is (x, y, z) = (-3, -1, 3).

Answer:
x < 1/2 and x>2
Step-by-step explanation:
first solve the eqn,
2x2 -5x +2 = 2x2 -4x -x +2 = 2x(x-2) - 1(x-2) = (2x-1)(x-2)
since the questions asks for >,
x < 1/2 and x>2
if the question had asked for <,
1/2<x<2

I promise this will work. If not, then ask me again and I'll try again.
Answer:
The answer is. C.
Step-by-step explanation:
If we have a function f(x) then we can move its graph horizontally making the transformation
Then if the graph will move c units to the left.
If the graph will move c units to the right.
If we apply the transformation then the graph of f(x) will move vertically h units.
If the displacement will be h units up
If the displacement will be h units down.
In this problem we have the parent function and we want to move 8 units to the left and 1 unit to the bottom.
Then we apply the transformations described above with .
Now we must move the function 1 unit down, with .
The correct answer is option C
