Answer:
-64
Step-by-step explanation:
The question is asking to solve
Notice how the -4 is in parenthesis. This means that along with the 4 being multiplied, the negative is too.
is the same as -4 · -4 · -4
First let's figure out if this will be negative or positive
Whenever the exponent is odd and there is a negative in the parenthesis the answer will be negative and if its even it will be positive
Now find out what 4 x 4 x 4 equals (64)
In conclusion the answer is -64
The system of equations is consistent and independent and the solutions are x = 4, y = 5, and z = -1 option third is correct.
<h3>What is a linear equation?</h3>It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have three linear equations in three variables:
x - y - z = 0 ..(1)
2x - y + 2z = 1 ..(2)
x - y + z = -2 ..(3)
From the equation (1):
Plug this value in the equation (2) and (3):
After solving we get:
z = -1
y = 5
Plug the above two values in equation (1) we get:
x = 4
Thus, the system of equations is consistent and independent and the solutions are x = 4, y = 5, and z = -1 option third is correct.
