\( r = \{ ( x , y ) | y = | x | - 5 \} \)

d) \( 16 \cdot 4^{15}:\left(8^{2} \cdot 4^{5}\right)=8^{x} \)

Solve the inequality. Express the solution set in set-builder notation and interval notation. Graph the solution set on a real number line. \( \frac{1}{2}(n-4)>n+5 \)

в) \( x+15 \frac{3}{17}=20 \frac{14}{17} \) \( x= \) \( x= \) \( x= \)

Graph the parabola. \[ y=(x+2)^{2}+4 \] Plot five points on the parabola: the vertex, two points to the left of the vertex, and two points to the right of the vertex. Then click on the graph-a-function button.

7. \( 2 x^{2}+x-4=0 \) \( \begin{array}{ll}\text { a. }-\frac{1}{2} \pm \frac{\sqrt{33}}{4} & \text { c. }-\frac{1}{4} \pm \frac{\sqrt{33}}{4} \\ \text { b. }-4 \pm \frac{\sqrt{66}}{4} & \text { d. }-\frac{1}{2} \pm \frac{\sqrt{33}}{2}\end{array} \)
