what does lily tell her friends to for me you are the 数字42有什么特别意义么? 999444633664 代表着什么.她给我发啦一这些数字,我回复了一句.她接着又回复啦：42. 数字128可以代表 我要发 42这个数代表的是什么省 解关于x的不等式:ax^2-(a+1)x+1>0,(a属于R) 小彬解方程(2x-1/5)+(x+a/2)时,方程左边的1没有乘10,由此得解x＝4,试求a的值,并正确求出方程的解. 小彬解方程（2X-1）/5+1=（X+A）/2是,方程左边的1没有乘以10,由此求得方程的解为X=4,试求A的值 已知：点M（a,b）在双曲线y=1/x上,点N与点M关于y轴对称,且点N在直线y=x+3上,则OM的长为多少 如果函数y=a^x+b的图像经过第二,三,四象限,则a,b的范围是 若a>1,-1y=a^x+b 已知a属于(2011π,2012π),且sin(a+2011π)=根号3/3,则cos(a-2012π) 描写的草原的古诗 双曲线x^/b^-y^/a^=1的两条渐近线互相垂直,那么该双曲线的离心率是? 双曲线x^2/144-y^2/b^2=1的两条渐近线互相垂直,那么它的离心率为? 七年级下生物练习册（四川教育出版社）第三章 人体的呼吸 第三节 空气质量与健康答案（P28~P30） 我听到外国人说,how long have you live there?你住在那儿多久了?但我认为应该是 how long do you live there?这两个句子有什么区别? How long have you been there? 我国地形特点对地理环境和经济发展有何影响 Tom was very poor,but now he is very rich.Every dog has its day. a rich man named Miser appeared in front of Tom．named是什么成分?为什么用ed形式?a rich man named Miser appeared in front of Tom．named是什么成分?为什么用ed形式?是形容词做定语吗? 数学.若双曲线x²/a²-y²/b²=1的离心率为√3,其渐近线的斜率为 若f（2X+1）=X方—2X 则f（3）=? F（X-1）+F(X+1)=X方-2X,求F(X).急/, Tom was such a clever and lovely boy that everyone liked him.和Tom was such a clever and lovely boy as everyone liked.有什么不同 Tom is ___ clever boy and___boy everyone likes to be with选项：A a;aB a;theC the;a Dthe;the Tom is very clever,so everyone calllshim a w no one can help ______Tom;he is suc a lovely boy.a.to likeb.to likingc.likingd.like 已知f(x)为二次函数且f(x+1)+f(x-1)=2x方-4x.求f(x) 若f(x)=2x-√(x方+4x+4),则f(a)=?!
