{12 x−15 y>−12y≥45\begin{cases}\frac12\ x-\frac15\ y>-\frac12\\y\geq\frac45\end{cases}{21 x−51 y>−21y≥54
{12 x−15 y>−12y≤45\begin{cases}\frac12\ x-\frac15\ y>-\frac12\\y\leq\frac45\end{cases}{21 x−51 y>−21y≤54
{12 x−15 y<−12y≤45\begin{cases}\frac12\ x-\frac15\ y<-\frac12\\y\leq\frac45\end{cases}{21 x−51 y<−21y≤54
{12 x−15 y<−12y≥45\begin{cases}\frac12\ x-\frac15\ y<-\frac12\\y\geq\frac45\end{cases}{21 x−51 y<−21y≥54
Type a concept, like “slope” or “photosynthesis”.
