lt was under the bed just now 对under the bed提问 what kind of dress does the lady want?翻译下 还有kind You have a kind of dress,but you can't put it on.What is it?谜语 如图,在直角坐标系中,B点的坐标为(2,2),点A为Y轴正半轴上一动点,过B作BC⊥AB交X轴正半轴与点C.当A点运动时,OA+OC的值是否发生变化,诺不变,求气质;若发生变化,求变化范围. 在直角坐标系平面内,A、B两点分别在x正半轴y正半轴上运动,线段AB的长为10,直线y=kx与AB交于点M,且平分三角形AOB的面积,那么动点M到原点的距离是否随着A、B点的变化而变化?为什么? 在直角坐标系中,B点的坐标为(2.2),A为Y轴上一动点,过B作BC⊥AB交X轴正半轴与点C,求证:BA=BC 一元二次方程超难题x²-kx+5(k-5)=0有两个正实数根,且2x1+x2=7 求k 关于一元二次方程的难题(高手来!)已知关于x的方程k^2x^2+(1-24)x+1=0有两个不相等的实数根x y (1)求k的取值范围 (2)当K为何值时,|x+y|-2xy=33 麻烦有绝对把握的再发上来啊,我做了感觉答案好像 有关、一元二次方程,一元二次方程是,一条直线把?1:是不是要知道两个点才能确定?2:知道两个点,如何解这方程(把它化成一元二次方程形式)3:斜率如果是正的,直线方向朝哪? 一元二次方程的难题 What kind of work do you want to do? Jack tried his best to do this work.(转换为同义句) Jack__________________to do this work. is it on the dresser怎么改为复数 They are (our) asketballs.My shoes are (under the bed).对括号内的部分进行提问.该如何做? The l----- is on the dresser 英语翻译 this is the kind of life he is used to为什么 he is used to 而不是 he used to His shoes are under the bed?(under the bed)对括号部分怎么提问?.Her brother's coat is red.(under the bed)对括号部分怎么提问?IS this your car?改为复数句式.Those are Mike's brown caps.改为单数句式. This is kind of life ;(Mary)is my friend.2;(The shoes) are under the bed.就画括号部分提问 The n___ is on the dresser.空处该填啥?是n打头的...请问“note、nail“是啥意思?拜托解释一下啦。。项链这个单词还没学哦。。 1;(Mary)is my friend.2;(The shoes) are under the bed.就画括号部分提问 有没有J Rice的Thank You For The Broken Heart歌曲链接?求各位大大发个、、、 There is a F____ book on the dresser. My h()is in my bag.Is the watch o()the table?The m()book is on the dresser.My bed is in my r().Is the cat here?--No,it is b()the sofa.My books are n()to his baseball.根据局以及首字母提示,写出单词,使句子完整! 如果关于x的不等式x<4x+5a和2x>4的解集相同,则a值为 《偶然》或者《牵手》命题的作文不用写太深奥,初三水平就可以了! 已知sinx=1/3,则sin2(π/4-x)= 已知sinx=(√5-1)/2,则sin2[x-(π/4)]= 已知sinX=(√5-1)/2,求sin2(X-π/4)的值 英语划线提问Your shoes are under the bed.对under the bed提问 已知关于X的不等式(5a+b)x6(x-1)+1的解集相同.求关于x的不等式ax-6b/2
