四字成语中的词类活用

某组织在2010年末有员工30万人,假定每年退休员工为上一年员工总数的a%,且每年新增员工m万人（m为常数）.记2010年末员工人数为b1,以后各年末的员工人数为b2,b3,b4…第一问：写出b2,b3的表达式 英语翻译George Gordon Byron SHE walks in beauty like the night Of cloudless climes and starry skies And all that's best of dark and bright Meets in her aspect and her eyes; Thus mellow'd to that tender light Which Heaven to gaudy day denies.One s 画勾的两个题, 画勾的第二题什么做 走廊的设计宽度一般为多少 concert,maybe,school,you,be,in,can,our(连词成句) 是Maybe you can in our school concert还是Maybe you can be in our school concert重点在于can后跟不跟be f（x）＝X十1,0≤X＜3 -1,x＜0 的定f（x）＝X十1,0≤X＜3-1,x＜0 的定义域及值域 设f(x)={x+3,x>10,f(x+5),x 5（1.2.3.4. 1,3,4,5第一个采纳 2(x+y)-3(x-y）＝7 ,3﹙x+y﹚＋5﹙x-y﹚＝1有几种不同的解法,那种解法比较方便 y=(x-3)(2-x)^2解法 已知X=1是方程2-三分之一乘（M-X）=2X的解,则m（x-3）-2=m（2x-5）的解是? 已知x乘y小于0 并且4x平方-9y平方=36 由此能否确定一个函数关系y=f(x) 若幂函数y=f(x)过点(9,1\3),则f(25)值为 can in concert be you school our（连词成句） a you are musician(连词成句)can't the play she piano(连词成句)well kids can't it play(连词成句)You can come here again(改成祈使句) 已知x1,x2是关于X的方程x^2+(2a-1)x+a^=0的两个实数根,且（x1+2）（x2+2）=11,求a的值.答：它不是已经说了x1 x2是两个实数根么 根据根与系数的关系 把x1 x2 用a替换 带入（x1+2）（x2+2）=11 得a^2-4a-5=0 a 已知：x1、x2是关于x的方程x^2+(2a-1)x+a^2=0的两个实数根且（x1+2)(x2+2)=11,求a的值 you look so _________(worry).what's wrong? don't_______(worry)a bout me. 解方程：（x+1）^4+(x+3)^4=82希望写出过程,详细点,谢谢! 解方程:x+3x-3+2x+4=97求详细解法 解方程:3分之(X+1)=6分之5（X+1）,—1.你有几种解法?你认为哪种解法简便. will you be my friend?lonely,you say 'i will'.then get the score.so simple.good luck.i'm male.
