Answer:
any point on the graph that's not shaded
Step-by-step explanation:
you can just plot any point on the graph that's not shaded(because it's not a solution to the inequality).
for example, (3, -5) or (-4, -5) or (7, 0)
Answer:
Yes. it is a function
Step-by-step explanation:
None of the x's axis are the same
Answer:
The system is consistent because the rightmost column of the augmented matrix is not a pivot column.
Step-by-step explanation:
It is given that the coefficient of the matrix of a linear equation has a pivot position in every row.
It is provided by the Existence and Uniqueness theorem that linear system is said to be consistent when only the column in the rightmost of the matrix which is augmented is not a pivot column.
When the linear system is considered consistent, then every solution set consists of either unique solution where there will be no any variables which are free or infinitely many solutions, when there is at least one free variable. This explains why the system is consistent.
For any m x n augmented matrix of any system, if its co-efficient matrix has a pivot position in every row, then there will never be a row of the form [0 .... 0 b].
