Answer 2

Answer: The correct option is C.

Step-by-step 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.

`A=\begin{bmatrix}6 & -3 & 3 & -1\end{bmatrix}`

`B=\begin{bmatrix}1 & -3 & -5 & -6\end{bmatrix}`

The difference of January and February is defined by the matrix A-B.

To subtract two matrices, we subtract all the corresponding elements.

`A-B=\begin{bmatrix}6-1 & -3+3 & 3+5 & -1+6\end{bmatrix}`

`A-B=\begin{bmatrix}5 & 0 & 8 & 5\end{bmatrix}`

It is the option C.
