Help me with these two

slavikrds [6]

To find the answer of the first one, plug in numbers for x, and see if they make the inequality true. Like, 5, 6, and 7.

For the second one, add 13 to both sides. The answer is 21.

Use a matrix to find the coordinates of the endpoints or vertices of the image of each figure under the given reflection.

The vertices of the original quadrilateral can be written in matrix form using the vertex matrix. The vertex matrix is
$\begin{pmatrix}-5&-1&-3&-7\\ 4&-1&-6&-3\end{pmatrix}$

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
$\begin{pmatrix}-1&0\\ 0&1\end{pmatrix}$

Multiplying the two matrices, we have
$\begin{pmatrix}-1&0\\ 0&1\end{pmatrix}\begin{pmatrix}-5&-1&-3&-7\\ 4&-1&-6&-3\end{pmatrix}=\begin{pmatrix}5&1&3&7\\ 4&-1&-6&-3\end{pmatrix}$

Therefore, the coordinates of the endpoints or vertices of the image are (5,4), (1,-1), (3, -6) and (7, -3).
