Answer: The correct option is C.
Explanation:
It is given that Jonas made the following matrix of temperatures for the first 4 days of January and for the first 4 days of February.
Let the matrix A and B represents the temperatures for the first 4 days of January and February respectively.
[tex]A=\begin{bmatrix}6 & -3 & 3 & -1\end{bmatrix}[/tex]
[tex]B=\begin{bmatrix}1 & -3 & -5 & -6\end{bmatrix}[/tex]
The difference of January and February is defined by the matrix A-B.
To subtract two matrices, we subtract all the corresponding elements.
[tex]A-B=\begin{bmatrix}6-1 & -3+3 & 3+5 & -1+6\end{bmatrix}[/tex]
[tex]A-B=\begin{bmatrix}5 & 0 & 8 & 5\end{bmatrix}[/tex]
It is the option C.
