Запишите системы линейных неравенств, эквивалентных квадратичному неравенству

\(\displaystyle -2x^2+6x+80\le0{\small.}\)

\(\displaystyle \left\{ \vphantom{\begin{aligned} 1\\[10px] 1 \end{aligned}} \right. \)	\(\displaystyle x\)[?|≤|≥|=|>|<][ ],
	\(\displaystyle x\)[?|≤|≥|=|>|<][ ]

или

\(\displaystyle \left\{ \vphantom{\begin{aligned} 1\\[10px] 1 \end{aligned}} \right. \)	\(\displaystyle x\)[?|≤|≥|=|>|<][ ],
	\(\displaystyle x\)[?|≤|≥|=|>|<][ ].
