14 Multiple Answer 1 point Choose the two equations that make up the system of linear inequalities. \( y \leq-3 \) \( y \geq-3 \) \( y<-3 \) \( y>-3 \) \( y \geq x-3 \) \( y \leq x-3 \) \( y \) \( \square \) \( \square \) \( y>x-3 \)

4. The factors of \( 2 x^{2}-8 \) are: \( 2\left(4 x^{2}\right) \) \( 2\left(x^{2}+4\right) \)

\( \left. \begin{array} { l l } { x ^ { 2 } - 4 } & { = y ^ { 2 } - 2 ^ { 2 } } \\ { y ^ { 2 } - 1 } & { = } \\ { 25 x ^ { 2 } - 36 } & { = } \\ { 16 - 81 a ^ { 2 } } & { = } \end{array} \right. \)

1) \( a^{2}-4 \)

stema \( \left\{\begin{array}{l}x+y=10 \\ 2 x-y=8\end{array}\right. \)

\( \left. \begin{array} { l } { x ^ { 2 } - x - 6 } \\ { x ^ { 2 } - x - 72 } \\ { x ^ { 2 } + 5 x - 6 } \\ { x ^ { 2 } - 4 x - 45 } \\ { x ^ { 2 } + 3 x - 18 } \end{array} \right. \)
