Answer:
Option A is correct.
Step-by-step explanation:
The following matrix represent the augmented matrix
In augmented matrix the left side represent the co-efficient of the variables and right side represent the value of variables.
Since the matrix has been solved and reduced so, the solution of variables x, y and z is written on right side of augmented matrix
The given matrix is:
Since the last row is all zero and we have a non zero entry for the solution, the matrix is inconsistent.
As the variables have zero values, there cannot be any solution
So, there is no solution.
So, Option A is correct.
The answer is 60 degrees,cause a straight line is 180
Answer:
C
Step-by-step explanation:
Since they're the same factor being raised to a power. Treat them as a log of 2.
Log² 48 - 38
Log² 2
= 2²
