z=0.015x*x+y*x*0.05+(1-x-y)*2.5*(x+y) x>0.35.x

问题描述:

z=0.015x*x+y*x*0.05+(1-x-y)*2.5*(x+y) x>0.35.x
y>0.70
x+y

0.55 *(1-x)的0.35 * X = 0.52
溶液:0.55-0 .55 x 0.35 X = 0.52
0.55倍-0.35X = 0.55-0.52
> 0.2×= 0.03
X = 0.15
我希望能帮助你!
不明白的地方欢迎追问.z=0.015x+y*x*0.05+(1-x-y)*2.5*(x+y)
x>0.35.x+y>0.70
x+y求z最大值?
