Matrices A and B shown below are equal.
1 answer:
Answer:
-18
Step-by-step explanation:
see attachment for the figure.
If the two matrices are equal. In this way, the amount in the upper, right-hand corner of A (which is - 18) is equivalent to the amount in the upper, right-hand corner of B, which is b₁₂
Therefore, the first answer choice (-18) is the correct one.

<h2>Answer:</h2><h3>False</h3><h2>Step-by-step explanation:</h2>
In this problem, we have the following System of Three Equations in Three Variables, so our goal is to determine whether is the solution to this system, that is, the ordered triple
where three planes intersect.
The easier way to find the answer is to plug in the x, y and z values in the equations and figure out whether the equations satisfy the solutions. Then:
STOP HERE! Since the x, y an z values doesn't satisfy the second equation, the is not the solution to the system of equations.
