过秦论读后感

求lim（x趋于1）(3x方-2x+1) lim x→∞(2x+1)/(3x-4) lim x→∞ (2x-2)\(3x-1)怎么求 填空 lim x趋于无穷 （2x-1）^20(3x-2)^20/(2x+1)^40=什么 （1.7-2x）/0.3=x/0.7-1,（3+0.2x）/0.2-(0.2+0.03x)/0.01=0.75 问：用整体求解法解：5（2x+3)-0.75(x-2)=2(x-2)-0.5(2x+3)还得有过程 128减3分之1x等于80x等于几 5（x-2.8）=140 用解方程 解方程 5（×-2.8）=140 2/3÷×=3/50 2：0.5=×：9 同学们参观“世博图片”展览,五年级去的人数比四年级多40人,是四年级去的人数的1.5倍,两个年级各去了多少人? 240x-180(x+5/6)=50怎么解 解方程：x+x／6=140 x/6-6=6解方程 6(20+x)-4x=140解方程, 已知代数式2x²+ax-y+6-2bx²+3x-5y-1的值与字母x的取值无关,求1/3a³-2b²-1/4a³+3b²的值 一次函数y=kx+b的图象经过平行于正比例函数y=0.5x的图像,且过点(4,7),求一次函数的解析式以及与坐标轴的交点坐标 一次函数y=kx+b的图像经过(-2,-10)且与正比例函数y=0.5x的图像相交于(4,a) 求A的值 一次函数y=kx+b的解析式 这两个函数图像与Y轴所围成的三角形的面积 一次函数y=kx+b的图像经过(-2,-10)且与正比例函数y=0.5x的图像相交于(4,a) 求A的值 若方程lg(ax^2-2x+2)=1在[1/2,2]内有解,求实数a的取值范围 求lim[(1+2x)^10(1+3x)^20/(1+6x^2)^15],x趋于无穷 求lim x趋向于无穷时(-X)/(2X^2+3x-1)答案 what does she do in the morning?请您帮我解释下.还有这句话是现在时,还是将来时. What does she do in the morning 和 What is she doing now 前句用 does 后句用is ,为什么? what does she do in the morning 这句话的结构,哪一个是主要动词? 1.what does she have in the morning?给出(milk,eggs ).我答的是:she eats milk and eggs in the morning.2.He come home at 6:00.要求写问句"他6点在什么地方?"我答:where is he at 6 o'clock? 方程lg(ax^2-2x+2)=1在[1/2,2]内有解,求实数a的取值范围 I don't know .What time does he often get up?合为一句 does underground leave what the time?[连词成句] what does the doctor ask mrs smith to eat every day? what does Tom do every day Tom usually gets up early in the morning.he h___breakfast at seven.Hehas breadnand milk f____breadfast.He g____workat about 7:30.He is never l_____for school.He has four c____in the morning.at about12he comes home for lunch What does Smith ask Green to do then what does cindy smith do?中文意思
