\( =4.9434 \) Taking anti-log, Antilog \( (\log x)= \) Antilog 49434 \( x=0.0000778 \) (b) If \( \left(5 x-\frac{1}{5 x}\right)=6 \), then Find the value \( \left(125 x^{3}-\frac{1}{125 x^{3}}\right) \). (Given)

Simplify the expression: \( 3 z-6+7-3 z+9 \)

Resolver \( \left\{\begin{aligned} x+2 y+z & =4 \\ 3 x+z & =2 \\ x-y+z & =7\end{aligned}\right. \)

Graph the solution set of the following system of inequalities. \[ \begin{array}{l}x+y \leq 4 \\ y \geq x^{2}-3\end{array} \]

Simplify the expression: \( -4 m+4 m-9 m-8 m-6 m \) Submit

\( \left. \begin{array} { r l r l } { 5 x + 3 x + 2 x } & { = } & { 7 y + 5 y - 9 y } & { = } \\ { 2 a + 4 a + 6 a } & { = } & { 2 a + 3 a - 5 a } & { = } \\ { 3 x + 5 x - 6 x } & { = } & { 10 x - 5 x + 12 x } & { = } \\ { - 5 y - 8 y } & { = } & { - 11 b - 7 b } & { = } \end{array} \right. \)
