If \(x<0\), which of the following is true? C \(x^3\) is positive. ( \(x^3\) is negative. \(x^2\) could be either positive or negative. I don't know.
Line 1 is defined by \(y=3 x+7\), and line 2 is perpendicular to line 1. What is the slope of line 2 ? \(\bigcirc-3\) O \(\frac{1}{3}\) \(\bigcirc-\frac{1}{3}\) O I don't know.
If \(x=\sqrt{25}\), which of the following is true? $$ \begin{aligned} & \text { C } x=5 \\ & x=-5 \\ & x=\pm 5 \\ & \text { I don't know. } \\ & \end{aligned} $$
If \(x^2=25\), which of the following is true? $$ \begin{aligned} & \bigcirc x=5 \\ & \bigotimes x=-5 \\ & \hdashline x=\pm 5 \\ & \text { idon't know. } \end{aligned} $$
Which of the following is equivalent to \(x^{-2}\) ? $$ \begin{array}{r} -x^2 \\ \frac{1}{x^2} \\ \sqrt{x} \end{array} $$ I don't know.
