1QB等于?人民币 炫舞里面1QB等于多少RMB?3Q x²-3x=0,求x值, 1QB等于多少Q点啊``````````` 关于学英语是否必要的话题,3人口语对话4分钟,急、、 求英语口语对话!English learning! 英语翻译1 3:00 2 4:10 3 5:15 4 6:30 5 7:45 6 8:10 请大神给我推荐2000元左右的手机 看看3000元买这个手机值吗?这手机是什么版本的? 5a的平方X的四次方-5a的平方y的四次方 1QB等于多少钱? 1QB等于几积分同上 1QB等于多少Q点?以前不是等于100点的么...为什么现在只等于10点的?之前买某个农场道具700Q点 都只给了6Q - -(黄钻) 可是为什么现在那个居然要70QB- - 也是700Q点...现在发现变成1QB=10Q点.很无语 已知函数有f(x)f(y)-f(xy)=3x+3y+6,求f(2008) 对于函数f(x) 在同一坐标系中 y1=f(x-19)与y2=f(99-x)的图像恒关于?对称 Our teacher often asks us to read the text____ A.aloud B.loudly C.loud Dnosily 现在是10:00,请问多长时间之后时针与分针第一次重合? 现在是12点,再过几分钟,时针和分针第一次重合?列方程解答 已知f(x)=1/x-lnx在区间(1,2)内有一个零点x0,若用二分法求X0的近似值(精确度0.1),则需要将区间对分的次数为? 已知函数f(x)对于任意的x,y属于R,都有f(x)•f(y)-f(xy)=3x 3y 6,则f(2008)等于? 已知函数f(x)对于任意的x,y∈R,都有f(x)*f(y)-f(xy)=3x+3y+6,则f(2008)= 已知函数f(x)对于任意的x、y属于R,都有f(x)f(y)-f(xy)=3x+3y+6,则f2008)=? Our teacher often asks us__________(listen)carefully. “SPEAK EENGLISH MORE OFTEN THAN JUST IN CLASS,"our english teacher said to us如何变为间接引语 Our teacher often asks us to ride____(safe) Our teacher often asks us ___ who he is describingA.guessB.guessesC.guessingD.to guess 初二英语报51-55小题选择题. 一百元钱等于几个十元?谢谢了,大神帮忙啊 My English teacher often e_____ me to speak English as much as possible in class.
