For  $4x-x^2$  find f(-5)

What are the degree and leading coefficient of the polynomial:   $-2+5w+10w^2-6w^5$  ?

• leading coefficient is -2 and degree is 5

• leading coefficient is -6 and degree is 8

• leading coefficient is -6 and degree is 5

• leading coefficient is 6 and degree is 5

 $\ -2t^5+14t^4-12t^3$  Factor completely

•  $-2t^3\left(t^2-7t+6\right)$  

•  $-2t^3\left(t^2+7t+6\right)$  

•  $-2t^3\left(t+7\right)\left(t-1\right)$  

•  $-2t^3\left(t-6\right)\left(t-1\right)$  

 $\frac{x^6y^{-8}}{x^4y^{-3}}$  Simplify and write the following with positive exponents:

•  $\frac{x^2}{y^5}$  

•  $x^2y^5$  

•  $\frac{y^5}{x^2}$  

•  $\frac{1}{x^2y^5}$  

 Solve $-12\le3-x<2$  and write in interval notatiionl

 $Solve\ and\ simplify:\ \ \frac{1}{4}x-\frac{1}{2}=\frac{2}{3}x+2$
