Answer 17

we need to graph the function for this


http://www.wolframalpha.com/input/?i=plot+4x%2B3y%5Cgeq+30%2C+x%2B3y+%5Cgeq+21%2C+x%5Cgeq+0%2C+y%5Cgeq+0

Answer 18

or u can use this site also

Answer 19

now after graphing u have to find the vertex of the region

there are three vertex in the region

\(\Large (0,10),(3,6) ~~and~~(21,0)\)

\(\Large C=5x+8y\)

now u have to find the value of \(\Large C\)

for all three vertex to see the \(\large maximum\) and \(\large minimum\)

\(\Large f(0,10)=5\times 0+8\times 10\\
\Large =80\)

\(\Large f(3,6)=5\times 3+8\times 6\\
\Large =63\)

\(\Large f(21,0)=5\times 21+8\times 0\\
\Large =105\)

so the minimum value of \(\huge C\) is \(\huge 63\)
