<h3>Answer: B) $878.28</h3>
================================================
Explanation:
She starts off $16.75 in debt
Later on she deposits $16.75 to get completely out of debt and make the balance 0. This is after depositing the $5.72
So far her balance is $5.72
Add on $872.56 to get 5.72+872.56 = 878.28
-------------
This is what your steps may look like
-16.75 + (5.72 + 16.75)
-16.75 + (16.75 + 5.72)
(-16.75+16.75) + 5.72
(0) + 5.72
5.72
5.72+872.56
878.28
Isolate the variable by dividing by 8. The answer will be A, x is greater than or equal to -4.

Answer with Step-by-step explanation:
Suppose that a matrix has two inverses B and C
It is given that AB=I and AC=I
We have to prove that Inverse of matrix is unique
It means B=C
We know that
B=BI where I is identity matrix of any order in which number of rows is equal to number of columns of matrix B.
B=B(AC)
B=(BA)C
Using associative property of matrix
A (BC)=(AB)C
B=IC
Using BA=I
We know that C=IC
Therefore, B=C
Hence, Matrix A has unique inverse .
