\[ =-3 x+6 \] \( y=9 \) \( \begin{array}{l}\text { What is the solution to the system of equations? } \\ (-21,9) \\ (9,-21) \\ (-1,9) \\ (9,-1)\end{array} \)

Simpept 3.13 - Multiplying Complex Numbers Sollowing expression: \( 2 i(5+3 i) \)

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

Give the domain of \( (x)=\frac{x+2}{2 x^{2}-5 x-18} \) using interval notation The domain of \( f(x) \) is:

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

\( - 8.3 + x = - 12.5 \quad [ - 5.2 ] \)
