设x,y满足3x-y-6≤0,x-y+2≧0,x+y≧0,若目标函数z＝ax+y(a＞0)的最大值为14,则a＝ A.1 B.2 C.23 D.53/9
设x,y满足3x-y-6≤0,x-y+2≧0,x+y≧0,若目标函数z＝ax+y(a＞0)的最大值为14,则a＝ A.1 B.2 C.23 D.53/9
设x,y满足3x-y-6≤0,x-y+2≧0,x+y≧0,若目标函数z＝ax+y(a＞0)的最大值为14,则a＝ A.1 B.2 C.23 D.53/9
y满足约束条件：3x-y-6≤0 x-y+2≥0 x≥0 y≥0,若目标函数z=ax+X和Y的最大值,这样可求出X＝4Y＝6,所以,题目变为已知4A+6B＝1求2/
