Answer:
Therefore, the inverse of given matrix is
Step-by-step explanation:
The inverse of a square matrix is such that
where I is the identity matrix.
Consider,
Therefore, the inverse of given matrix is
Answer: X= 6 or X=-4
Step-by-step explanation:
The inequality can be:
Now you divide both sides by 150 to get the #of boxes.
Lastly, x is 20. So the maximum amount of boxes that the freight elevator can hold is 20
Rational sets also known as ratios
Use the equation
For A. The problem would be set up like so
5 _ -1
--------
4 _ -2
Start by subtracting 5 minus -1 which is 6 because minus a negative becomes a positive then subtract 4 minus -2 which is 6, remember minus a negative becomes a positive, then divide 6/6 to get 1
For B.
-5 _ -0
----------
3 _ -1
Again subtract -5 by -0 which no matter what will be -5. Then make -1 positive because it's a subtracted negative so it becomes 3+1 which gives you 4. Your answer is -5/4
