Решите систему неравенств: 10x^2-9x+2<=0; 14-2x<=0.

\[\left\{ \begin{matrix} 10x² - 9x + 2 \leq 0\ \ \ \ \ \ \ \ \\ 14 - 2x \leq 0,\ \ x \geq 7 \\ \end{matrix} \right.\ \]

\[10x^{2} - 9x + 2 = 0\]

\[D = 81 - 80 = 1\]

\[x_{1} = \frac{9 + 1}{20} = \frac{1}{2} = 0,5\]

\[x_{2} = \frac{9 - 1}{20} = \frac{2}{5} = 0,4\]

\[Ответ:\ \varnothing.\]
