It made the government realize that radio should only be used for point-to-point communications. It caused a panic that made ships' wireless operators stage a strike. It was a setback to the industry because some wireless prototypes were lost in the ship's wreckage.

For numbers \( 5-13 \), a) plot the following systems of inequalities; b) determine whether they are bounded or unbounded; and c) find all corner points \( \begin{array}{l}\text { 5-7). } \quad y \leq-3 x+3 ; y \geq-2 x+6 \\ \text { 8-10). } x-2 y+2 \geq 0 ; 4 x+y+5 \geq 0 ; 4 x-y \leq 6 \\ \text { 11-13). } x+20 y \leq 46 ; 21 x+2 y+2 \leq 86 ; x \geq 0 ; y \geq 0\end{array} \)
