若函数f(x)是定义域R上的偶函数,在(-∞,0]上是减函数,且f(2)=0,则使f(x) x分之一＋2=0是不是一元一次方程? x分之1 + 1 =2分之x 是一元一次方程吗? 若f(x)是定义域在│x│xㅌR,且x≠0上的偶函数,在(负无穷大0)上是增函数,且f若f(x)是定义域在│x│xㅌR,且x≠0上的偶函数,在(负无穷大0)上是增函数,且f（-3）=0.求使f（x）＞0的x的取值范 若关于x的方程x+m/x-3=m无解,求M的值什么是增根?我是这么解的,两边同时乘以x-3,变成x+m=m(x-3)设x=2.2+m=-m,m=-1.x-1=-(x-3)设x=4.3=1,因为无解,所以m=-1..到底这么做,知道的速度发,（x+m）/（x-3）=m没打清 已知方程2/X-M/X^2-X＝1+1/x-1,求是否存在M的值使方程无解 若关于x的方程(x-2)/(x-3)=m/(x-3) +2无解,则m值为?急…………………………………………………………………………………………………………………………………………………………………… 若方程(x-3)/(x-2)=m/(2-x)无解,求m的值,求个位详细一点, 英语作文,帮忙改下语法错误啊,Cristiano RonaldoI saw Cristiano Ronaldo for the first time when I was about fifteen years old.On that day,my father and I was watching the football games at midnight.At that time it was the 2010 FIFA World Cu 可以帮我改下语法错误吗?英语 作文以下是 我的作文The film ‘Les yeux sans visag’e is a relic of black-and-white cult filmin 1960s.The story theme is not new,but it is one of the most graceful andvisually sumptuous horror films. 请帮我修改一下英语作文,讲城市和乡村生活的区别.好处坏处和共同点.life in a city is very comfortable ,there has kinds of restrounds and apartments around the city .we can go anywhere by car ,taxi or bus.on weekends,we often 英语作文帮改语法错误Dear Mr.Smith,I'm Li Min.Due to rain,I have a cold and is sneezing and coughing.Unfortunately,I have to go to hospitalchecking and injection.I 'm begging you to approve one day leave for me tomorrow.Today's homework,I'll 帮忙改下英语作文的语法错误留一下邮箱,我发过去是大学英语作文,好几百字 若关于x的方程ax^2+bx+c=0是一元一次方程,则a,b,c的取值范围分别是 关于x的一元一次方程ax的二次方+bx+c=0(a不等于0）当a,b,c,满足什么条件时,方程的两根互为相反数? 含绝对值和根号的不等式题目是:根号(x+5) 已知幂函数f(x)=x^(-1/2p+p+3/2)(p属于z)在（0,正无穷大）上是增函数且在定义域上是偶函数p=1,f(x)=x^2设g(x)=f(x)-2qx+z+2q,问是否存在实数q,使得g(x)在区间[0,2]上有最小值-2?若存在,求出q的值;若不存在, 已知幂函数f（x）=x^(-P^2/2+p+3/2)(p∈z),在（0,正无穷）上是增函数,且在其定义域是偶函数,求p得值,并写出相应的函数f（x） 已知幂函数f（x）=x^-1/2p²+p+3/2 （p∈Z）在（0,+∞）上是增函数,且定义域内是偶函数,求P的值和相应的函数解析式 已知幂函数f(x)=x^(m^2-2m-3),m属于Z为偶函数,且区间(0,正无穷大)上是单调减函数,求函数f(x)要过程 已知幂函数f(x)=x^(3-p) (p∈正整数)在(0,+∞)上是增函数,且在其定义域内是偶函数,求p的值RT 若x=2是方程ax-2=3x的解,求a的值 若关于x的方程ax+3x=2的解是x=1/4,则a的值是多少? 求英语大神看此英语短文是否有语法错误,若有,求指出.Ms.Zhao often tell us something about two boys,and praises them for their clever.
