Answer:
Determinant = -12
Step-by-step explanation:
rewrite the system as
-2 = 2x - 3y + 0z
0 = 0x + y - 2z
1 = -3x + 2y - z
then the coefficient matrix is
{ [2, -3, 0]
[0, 1, -2]
[-3, 2, -1] }
to find determinant
{ [2, -3, 0] , 2, -3
[0, 1, -2] , 0, 1
[-3, 2, -1] }, -3, 2
determinant = 2*1*-1 + (-3 * -2 * -3) + (0*0*2) - 0 - (2*-2*2) - 0
determinant = -2 - 18 + 0 - 0 + 8 = -12
Answer: The correct answer should be 7.6128
If you do the problem correctly, you will get an answer of 7.6128. This is because there are 4 decimals places in the numbers that are being multiplied. This means that there will be 4 decimal places in the answer. If you have her work, we can find the mistake. It is probably that she counted the wrong number of places.
Answer:
10
Step-by-step explanation:
Here, we want to get the biggest number of spoon or forks that the bucket will have
What we have to do here is to simply find the greatest common factor of 100 and 80
Finding the greatest common factor of both will
give the biggest number of spoon or forks that the bucket will have
Mathematically, the greatest common factor of 80 and 100 is 10
