Solve for x and y matrix

charle [14.2K]

Answer:

$x=-1$

$y=5$

Step-by-step explanation:

$\begin{pmatrix}x&y\\ \:-1&4\end{pmatrix}\begin{pmatrix}2&5\\ \:4&1\end{pmatrix}=\begin{pmatrix}18&0\\ \:14&-1\end{pmatrix}$

$\begin{pmatrix}x&y\\ -1&4\end{pmatrix}\begin{pmatrix}2&5\\ 4&1\end{pmatrix}$

$=\begin{pmatrix}x\times \:2+y\times \:4&5x+y\\ 14&-1\end{pmatrix}$

$=\begin{pmatrix}18&0\\ 14&-1\end{pmatrix}$

$\begin{bmatrix}x\times \:2+y\times \:4=18\\ 5x+y=0\end{bmatrix}$

$x=-1$

$y=5$

Which is bigger 0.17 or 0.165

Bogdan [553]

0.17 is bigger because you compare the values of the number in each place. There is no whole number, the tenths place is equal. Then in the hundredths place you have a 6 and a 7. 6<7 so therefore 0.17> 0.165. To help yourself out u can add a 0 at the end to then more easily compare .170 to .165
