Answer:
you have the answer right tho:(
Step-by-step explanation:
The product of the matrices is an identity matrix. Then Both the matrices are multiplicative inverse to each other.
<h3>What is the matrix?</h3>
A matrix is a specific arrangement of items, particularly numbers. A matrix is a row-and-column mathematical structure. The a_{ij} element in a matrix, such as M, refers to the i-th row and j-th column element.
The matrices are given below.
Then show that both the matrices are multiplicative inverse to each other.
If the product of the matrices is an identity matrix then the matrices are multiplicative inverse to each other.
Then we have
Then both the matrices are multiplicative inverse to each other.

Point are set up (x,y) you sub the number for x into the equation and see if you get the number for y.
y=4x+3
y=4 (5)+3
y=20+3
y=23
so A isn't the answer
y=4 (17)+3
y=68+3
y=71
B isn't the answer
y=4 (4)+3
y=16+3
y=19
and because 4 is the x value for c and d and there can only be 1 y value for each x you're answer is C because when x=4 y =19 or (4,19)
