Question

i need work and help, anybody?!
Find the minimum and maximum for P = 3x + y.
Vertices are (0,0), (4, 0), (3, 4), (0, 10).

Answer 1

then your job is to replace \(x\) by 0, \(y\) by 0 and compute
then replace \(x\) by 4, \(y\) by 0 and compute
then replace \(x\) by 3,\(y\) by 4 and compute and finally
replace \(x\) by 0, \(y\) by 10 and compute
the biggest is the max, the smallest is the min

Answer 2

for example, the second point \((4,0)\) gives
\[p=3\times 4+0=12\][

Answer 3

im still confused, i dont get this at all
