Answer: 4.33333333333 hope this helps
Step-by-step explanation:
Answer:No because if you add 5 plus 4 you will get nine but when u subtract 5 from four you will get 1 so no it would not get you any of those

The vertices of the original quadrilateral can be written in matrix form using the vertex matrix. The vertex matrix is
![\begin{pmatrix}-5&-1&-3&-7\\ 4&-1&-6&-3\end{pmatrix}](https://tex.z-dn.net/?f=%5Cbegin%7Bpmatrix%7D-5%26-1%26-3%26-7%5C%5C%204%26-1%26-6%26-3%5Cend%7Bpmatrix%7D)
To find the coordinates of the endpoints or vertices of the image of the given coordinate points reflected about the y-axis, we just need to multiply the transformation matrix by the vertex matrix. The transformation matrix for this particular problem is
![\begin{pmatrix}-1&0\\ 0&1\end{pmatrix}](https://tex.z-dn.net/?f=%5Cbegin%7Bpmatrix%7D-1%260%5C%5C%200%261%5Cend%7Bpmatrix%7D)
Multiplying the two matrices, we have
![\begin{pmatrix}-1&0\\ 0&1\end{pmatrix}\begin{pmatrix}-5&-1&-3&-7\\ 4&-1&-6&-3\end{pmatrix}=\begin{pmatrix}5&1&3&7\\ 4&-1&-6&-3\end{pmatrix}](https://tex.z-dn.net/?f=%5Cbegin%7Bpmatrix%7D-1%260%5C%5C%200%261%5Cend%7Bpmatrix%7D%5Cbegin%7Bpmatrix%7D-5%26-1%26-3%26-7%5C%5C%204%26-1%26-6%26-3%5Cend%7Bpmatrix%7D%3D%5Cbegin%7Bpmatrix%7D5%261%263%267%5C%5C%204%26-1%26-6%26-3%5Cend%7Bpmatrix%7D)
Therefore, the coordinates of the endpoints or vertices of the image are
(5,4), (1,-1), (3, -6) and (7, -3).
