A certain brand of razor blades comes in packages of \(6,12\) and 24 blades, costing 2 dollar , 3 dollar, and 4 dollar per package, respectively. A store sold 12 packages containing a total of 162 razor blades and took in 35 dollar. How many packages of each type were sold?
Describe how the system $$\left\\{\begin{aligned} x+y-z-2 w &=-8 \\ x-2 y+3 z+w &=18 \\ 2 x+2 y+2 z-2 w &=10 \\ 2 x+y-z+w &=3 \end{aligned}\right.$$ could be solved. Is it likely that in the near future a graphing utility will be available to provide a geometric solution (using Fintersecting graphs) to this system? Explain.
write the partial fraction decomposition of each rational expression. $$ \frac{5 x^{2}+6 x+3}{(x+1)\left(x^{2}+2 x+2\right)} $$
write the partial fraction decomposition of each rational expression. $$ \frac{4}{2 x^{2}-5 x-3} $$
How can you verify your result for the partial fraction decomposition for a given rational expression without using a graphing utility?
