Simplify, \( 4 \sqrt{8}-\sqrt{50} \)

Find the domain of \( f(x)=\frac{\frac{3}{x-1}}{\frac{1}{x-2}+4} \) \( \begin{array}{l}\text { a) } R-\{1,2\} \\ \text { b) } R-\{1,7\} \\ \text { c) } R-\{1,2,7\} \\ \text { d) } R-\left\{1,2, \frac{7}{4}\right\}\end{array} \)

Simplify. \[ \sqrt[3]{\frac{1}{216}} \]

250 Resolver: a) \( -\frac{7}{4}+\frac{5}{4}= \)

Determine the slope of the line through the given points. If the slope is undefined, so state. \[ (-2,-4) \text { and }(12,-9) \]

Write \( \sqrt{-192} \) in simplest radical form
