x、y满足的约束条件0

x、y满足的约束条件0 设X,Y满足约束条件X+Y 线性规划的一道题已知变量x,y满足约束条件x+y-1=0x-y-1 满足约束条件(绝对值x)+2(绝对值y) 已知变量x,y满足约束条件1 已知x,y满足约束条件1 已知x,y满足约束条件x-y+5>=0 x+y>=0 X 已知x,y满足约束条件：x-y+1>=0,x+y-2>=0,x 已知X,Y满足约束条件x-y+5>=0 x+y>=0 X 设x,y满足约束条件x>=0 x>=y 2x-y 设x,y满足约束条件{x>=0,y>=x,4x+3y 设x,y满足约束条件x>=0 y>=x 4x+3y 当实数x,y,满足约束条件{x>0 y>=x 2x+y+k 实数x,y满足约束条件.求范围实数x,y满足约束条件x-y+2>=0 x+y-4>0x 设变量X,Y满足约束条件{X-Y+3>=0,X+Y>=0,-2 设变量x,y满足约束条件:x-y+3>=0 x+y>=0 -2 设变量x,y满足约束条件{x-y≥0,x+y≥0,2x+y≤1},则y/(x+1)的最大值?约束条件已会画图,关...设变量x,y满足约束条件{x-y≥0,x+y≥0,2x+y≤1},则y/(x+1)的最大值?约束条件已会画图,关键是y/(x+1)不会画 没有 若实数x,y满足约束条件x-y≥0,x+y≥0,2x+y≤1,则y/(x+1)的最大值是多少,
