Answer:
This relationship is a function
Step-by-step explanation:
While a function may not have two output values (y) assigned to the same input value (x), it may have two input values (x) assigned to the output value (y).
The table follows that rule
Answer:
Step-by-step explanation:
Add 9 to both sides:
Subtract 6a from both sides:
Divide both sides by -8:
Answer:
Remember, a homogeneous system always is consistent. Then we can reason with the rank of the matrix.
If the system Ax=0 has only the trivial solution that's mean that the echelon form of A hasn't free variables, therefore each column of the matrix has a pivot.
Since each column has a pivot then we can form the reduced echelon form of the A, and leave each pivot as 1 and the others components of the column will be zero. This means that the reduced echelon form of A is the identity matrix and so on A is row equivalent to identity matrix.
