Найдите значение выражения: -6x при x=-3,5; -1; 0; 2 1/12.

Ответ:

\[- 6x\]

\[x = - 3,5:\ \ \]

\[- 6 \cdot ( - 3,5) = 21.\]

\[x = - \ 1:\]

\[- 6 \cdot ( - 1) = 6.\]

\[x = 0:\]

\[- 6 \cdot 0 = 0.\]

\[x = 2\frac{1}{12} = \frac{25}{12}:\]

\[- 6 \cdot \frac{25}{12} = - \frac{6 \cdot 25}{12} =\]

\[= - \frac{25}{2} = - 12,5.\]
