Rationalize the denominator \( \frac{6-5 i}{2+i} \)

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

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

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

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

Jason earns an hourly wage of \( y \) dollars. If he works \( h \) hours in a week, write a linear expression representing his weekly earnings.
