\( \begin{array}{llll}8 . & 2 x=\sqrt{24+4 x} & \text { b. }-3 & \text { c. } 3 \text { and }-2\end{array} \)

Solve the inequality. Graph the solution. \( \begin{array}{lll}\text { (7) } 5.8 y+5<3 & \text { 6. } 3 p+2 \geq-10 & \text { 7. } 2>8-\frac{4}{3} h \\ \text { 8. }-2>\frac{m}{6}-7 & \text { 9. }-1.2 b-5.3 \geq 1.9 & \text { 10. }-1.3 \geq 2.9-0.6 r\end{array} \)

3. \( x^{2}-25=0 \)

\( \begin{array}{lll}\text { 5. } 8 y+5<3 & \text { 6. } 3 p+2 \geq-10 & \text { 10. }-1.3 \geq 2.9-0.6 r \\ \text { 8. }-2>\frac{m}{6}-7 & \text { 9. }-1.2 b-5.3 \geq 1.9 & \text { 10. }\end{array} \)

What are \( a \) and \( b \) when you write \( \sqrt{-16} \) in the form \( a+b i \), where \( a \) and \( b \) are real numbers?

5. \( z^{2}+z-12=0 \)
