x^2+y^2+1/2=s+y,则x=?,y=?x^2+y^2+1/2=s+y,则x=?,y=?x^2+y^2+1/2=s+y,则x=?,y=?x²+y²+1/2=x+yx&sup
x^2+y^2+1/2=s+y,则x=?,y=?
x^2+y^2+1/2=s+y,则x=?,y=?
x^2+y^2+1/2=s+y,则x=?,y=?
x²+y²+1/2=x+y
x²-x+1/4+y²-y+1/4=0
(x-1/2)²+(y-1/2)²=0
平方数不小于0,要使式子的值为0,则有
x-1/2=0,y-1/2=0
x=1/2,y=1/2
x^2+y^2+1/2 = x+y
x^2 - x + 1/4 + y^2 - y + 1/4 = 0
(x-1/2)^2 + (y-1/2)^2 = 0
如果x, y 是实数
那么 x=y=1/2
x^2+y^2+1/2=x+y
x^2-x+1/4+y^2-y+1/4=0
则(x-1/2)^2+(y-1/2)^2=0
则x=1/2
y=1/2
因为x=y,所以2x=2y,所以2s-(x+y)=2y-(x+y),即x-y=y-x则(x-y)/(y-x)/(x-y)对不对
x^2+y^2+1/2=s+y,则x=?,y=?
x-y/x-x+y/y-(x+y)(x-y)/y² y/x=2
S=(x+1/y)+(x^2+1/y^2)+.+(x^n+1/y^n)
已知全集S={(x,y)|x^2+y^2
设环形轨道长度为S,甲乙两辆汽车模型速度分别为x、y,则 S=(x+y)4/3.(1) S/x=4S/y.(2) 为什么S/x(甲的速度)会等于4S/y.
若实数x,y满足4^x+4^y=2^(x+1)+2^(y+1),则S=2^x+2^y的取值范围
已知集合S={y/y=2^x},集合T={x/ln(x-1)
(x-y)(x+y)-(x+y)^2+2y(y-x),其中x=1,y=3.
2y(x+二分之一y)-[(x+y)(x-y)+2y(y+x)],其中|x-1|=2
若集合S={(x,y)/x+y=0},T={(x,y)x-y=-2},则S交T=
若实数x,y满足2x*X+3y*y=1,S=3x*x-2y*y,则S的取值范围为叩谢……
已知x+y=a,2x-y=-2a,求[(x/y-y/x)/(x+y)-x(1/x-1/y)]/[(x+1)/y]的值
若2/x-1/y=3,求[y/x-y/x-y(x-y/x-x+y)]/x-2y/x的值
集合s={y|y=3^x},T={y|y=x^2-1},则S∩T=
请问S=max{2x+y ,
若x+y=4,则多项式1/2(x+y)+4(x-y)-3(x-y)-3/2(x+y)-x+y值是()
已知x,y∈R,y>=|x-1|,y=0则目标函数S等于2x-y的最大值
