Graph each inequality. $$ y \leq|x| $$

Graph the line passing through the given point with the given slope. $$ (-3,-1), m=-\frac{1}{5} $$

Write an equation in slope-intercept form for the line that satisfies each set of conditions. passes through \((2,-5),\) perpendicular to the graph of \(y=\frac{1}{4} x+7\)

Determine whether each function is discrete or continuous. $$ \\{(-3,0),(-1,1),(1,3)\\} $$

Graph each function. Identify the domain and range. \(h(x)=|-x|\)

Graph each inequality. $$ y > |4 x| $$

Graph the line passing through the given point with the given slope. $$ (3,-4), m=2 $$

Suppose the temperature \(T\) in \(^{\circ} \mathrm{F}\) above the Earth's surface is given by \(T(h)=-3.6 h+68,\) where \(h\) is the height (in thousands of feet). Find the height if the temperature is \(-58^{\circ} \mathrm{F} .\)

REVIEW Anna took brownies to a club meeting. She gave half of her brownies to Sarah. Sarah gave a third of her brownies to Rob. Rob gave a fourth of his brownies to Trina. If Trina has 3 brownies, how many brownies did Anna have in the beginning? $$ \begin{array}{l}{\mathrm{F} 12} \\ {\mathrm{G} 36} \\ {\mathrm{H} 72} \\\ {\mathrm{J} 144}\end{array} $$

COLLEGE For Exercises 22 and \(23,\) use the following information. Rosa's professor says that the midterm exam will count for 40\(\%\) of each student's grade and the final exam will count for 60\(\% .\) A score of at least 90 is required for an A. The inequality \(0.4 x+0.6 y \geq 90\) represents this situation, where \(x\) is the midterm score and \(y\) is the final exam score. Graph this inequality.
