名校课堂九年级数学答案
一、选择题
1. （2012四川成都3分）分式方程 的解为【 】
A．x=1 B． x=2 C． x=3 D． x=4
【答案】C。
【考点】解分式方程。
【分析】由 去分母得：3x﹣3=2x，移项得：3x﹣2x=3，合并同类项得：x=3。
检验：把x=3代入最简公分母2x（x﹣1）=12≠0，故x=3是原方程的解。
∴原方程的解为：x=3。故选C。
2. （2012四川成都3分）一件商品的原价是100元，经过两次提价后的价格为121元，如果每次提价的百分率都是x，根据题意，下面列出的方程正确的是【 】
A．100（1＋x）=121 B． 100（1－x）=121 C． 100（1＋x）2=121 D． 100（1－x）2=121
【答案】C。
【考点】由实际问题抽象出一元二次方程（增长率问题）。
【分析】由于每次提价的百分率都是x，第一次提价后的价格为100(1＋x)，
第一次提价后的价格为100(1＋x) (1＋x) ＝100(1＋x)2。据此列出方程：100（1＋x）2=121。 故选C。
3. （2012四川攀枝花3分）下列说法中，错误的是【 】
A． 不等式x＜2的正整数解中有一个 B． ﹣2是不等式2x﹣1＜0的一个解
C． 不等式﹣3x＞9的解集是x＞﹣3 D． 不等式x＜10的整数解有无数个
【答案】C。
【考点】不等式的解集。
【分析】解不等式求得B，C选项的不等式的解集，即可判定C错误，由不等式解的定义，判定B正确，然后由不等式整数解的知识，即可判定A与D正确。故选C。
4. （2012四川攀枝花3分）已知一元二次方程：x2﹣3x﹣1=0的两个根分别是x1、x2，则x12x2+x1x22的值为【 】
A． ﹣3 B． 3 C． ﹣6 D． 6
【答案】A。
【考点】一元二次方程根与系数的关系，求代数式的值。
【分析】由一元二次方程：x2﹣3x﹣1=0的两个根分别是x1、x2，
根据一元二次方程根与系数的关系得，x1+x2=3，x1x2=―1，
∴x12x2＋x1x22=x1x2（x1＋x2）=（－1）•3=－3。故选A。
5. （2012四川宜宾3分）分式方程 的解为【 】
A． 3 B． ﹣3 C． 无解 D． 3或﹣3
【答案】C。
【考点】解分式方程。
【分析】因为方程最简公分母为：（x+3）（x﹣3）。故方程两边乘以（x+3）（x﹣3），化为整式方程后求解：
方程的两边同乘（x+3）（x﹣3），得12﹣2（x+3）=x﹣3，
解得：x=3．
检验：把x=3代入（x+3）（x﹣3）=0，即x=3不是原分式方程的解。
故原方程无解。
故选C。
6. （2012四川广安3分）已知关于x的一元二次方程（a﹣l）x2﹣2x+l=0有两个不相等的实数根，则a的取值范围是【 】
A．a＞2 B．a＜2 C．a＜2且a≠l D．a＜﹣2
【答案】C。
【考点】一元二次方程根的判别式，一元二次方程定义。
【分析】利用一元二次方程根的判别式列不等式，解不等式求出a的取值范围，结合一元二次方程定义作出判断：
∵由△=4﹣4（a﹣1）=8﹣4a＞0解得：a＜2。
又根据一元二次方程二次顶系数不为0的定义，a﹣1≠0，∴a＜2且a≠1。故选C。
7. （2012四川内江3分）甲车行驶30千米与乙车行驶40千米所用时间相同，已知乙车每小时比甲车多行驶15千米，设甲车的速度为 千米/小时，依据题意列方程正确的是【 】
A. B. C. D.
【答案】C。
【考点】由实际问题抽象出方程（行程问题）。
【分析】∵甲车的速度为 千米/小时，则乙甲车的速度为 千米/小时
∴甲车行驶30千米的时间为 ，乙车行驶40千米的时间为 ，
∴根据甲车行驶30千米与乙车行驶40千米所用时间相同得 。故选C。
8. （2012四川达州3分）为保证达万高速公路在2012年底全线顺利通车，某路段规定在若干天内完成修
建任务.已知甲队单独完成这项工程比规定时间多用10天，乙队单独完成这项工程比规定时间多用40天,
如果甲、乙两队合作，可比规定时间提前14天完成任务.若设规定的时间为x天，由题意列出的方程是【 】
A、 B、
C、 D、
【答案】B。
【考点】由实际问题抽象出分式方程（工程问题）。
【分析】设规定的时间为x天．则甲队单独完成这项工程所需时间是（x+10）天，乙队单独完成这项工程所需时间是（x+40）天．甲队单独一天完成这项工程的 ，乙队单独一天完成这项工程的 ，
甲、乙两队合作一天完成这项工程的 ，则 。故选B。
9. （2012四川德阳3分）为确保信息安全，信息需加密传输，发送方由明文→密文（加密）；接收方由密文→明文（解密）.已知加密规则为：明文a，b，c，d对应密文， ， ， ， .例如：明文1，2，3，4对应的密文5，7，18，16.当接收方收到密文14，9，23，28时，则解密得到的明文为【 】
A. 4，6，1，7 B. 4，1，6，7 C.6，4，1，7 D.1，6，4，7
【答案】C。
【考点】多元一次方程组的应用。
【分析】已知结果（密文），求明文，根据规则，列方程组求解：依题意，得
，解得 。故选C。
10. （2012四川绵阳3分）已知a＞b，c≠0，则下列关系一定成立的是【 】。
A．ac＞bc B． C．c-a＞c-b D．c+a＞c+b
【答案】D。
【考点】不等式的性质。
【分析】根据不等式的基本性质进行判断即可：
A、当c＜0时，不等式a＞b的两边同时乘以负数c，则不等号的方向发生改变，即ac＜bc．故本选项错误；
B、当c＜0时，不等式a＞b的两边同时除以负数c，则不等号的方向发生改变，即 ．故本选项错误；
C、在不等式a＞b的两边同时乘以负数-1，则不等号的方向发生改变，即-a＜-b；然后再在不等式的两边同时加上c，不等号的方向不变，即c-a＜c-b．故本选项错误；
D、在不等式a＞b的两边同时加上c，不等式仍然成立，即a+c＞b+c；故本选项正确。 故选D。
11. （2012四川凉山4分）设a、b、c表示三种不同物体的质量，用天枰称两次，情况如图所示，则这三种物体的质量从小到大排序正确的是【 】
A． B． C． D．
【答案】A。
【考点】等式和不等式的性质。
【分析】观察图形可知：b＋c =3c，即b = 2c ；且a＞b。所以 。故选A。
12. （2012四川凉山4分）雅西高速公路于2012年4月29日正式通车，西昌到成都全长420千米，一辆小汽车和一辆客车同时从西昌、成都两地相向开出，经过2.5小时相遇，相遇时，小汽车比客车多行驶70千米，设小汽车和客车的平均速度分别为x千米/小时和y千米/小时，则下列方程组正确的是【 】
A． B．
C． D．
【答案】D。
【考点】由实际问题抽象出二元一次方程组（行程问题）。
【分析】设小汽车和客车的平均速度分别为x千米/小时和y千米/小时，
根据相遇时，小汽车比客车多行驶70千米可列方程2.5x－2.5y=70；
根据经过2.5小时相遇，西昌到成都全长420千米可列方程2.5x＋2.5y=420。
故选D。
13. （2012四川泸州2分）若关于x的一元二次方程x2 －4x + 2k = 0有两个实数根，则k的取值范围是【 】
A、k≥2 B、k≤2 C、k＞-2 D、k＜-2
【答案】B。
【考点】一元二次方程根的判别式，解一元一次不等式。
【分析】由于已知方程有两个实数根，根据一元二次方程的根与判别式的关系，建立关于k的不等式，解不等式即可求出k的取值范围：
∵a＝1，b＝－4，c＝2k，且方程有两个实数根，
∴△＝b2－4ac＝16－8k≥0，解得，k≤2。故选B。
14. （2012四川泸州2分）已知三角形两边的长分别是3和6，第三边的长是方程x2 - 6x + 8 = 0的根，则这个三角形的周长等于【 】
A、13 B、11 C、11 或13 D、12或15
【答案】A。
【考点】因式分解法解一元二次方程，三角形三边关系。
【分析】首先由方程x2－6x＋8＝0，确定第三边的边长为2或4；其次考查2，3，6或4，3，6能否构成三角形，从而求出三角形的周长：
解方程x2－6x＋8＝0，得：x1＝2或x2＝4。
当第三边是2时，2＋3＜6，不能构成三角形，应舍去；
当第三边是4时，三角形的周长为4＋3＋6＝13。故选A。
15. （2012四川南充3分）方程x（x-2）+x-2=0的解是【 】
（A）2 （B）-2,1 （C）－1 （D）2,－1
【答案】D。
【考点】因式分解法解一元二次方程。
【分析】先利用提公因式因式分解，再化为两个一元一次方程，解方程即可： 由x（x﹣2）+（x-2）=0，得（x-2）（x+1）=0，∴x-2=0或x+1=0， ∴x1=2，x2=-1。故选D。

Today almost everyone knows computers and the Internet. If I ask you “What is the most important in your life?” maybe you will say “Computers and the Internet.”
The first computer was made in 1946. it was very big but it worked slowly. Today computers are getting smaller and smaller. But they work faster and faster. What can computers do? A writer has said, “People can’t live without computers today.”
The Internet came a little later than computers. It is about twenty-five years later than computers. But now it can be found almost everywhere. We can use it to read books, writer letters, do shopping, play computer games or make friends.
Many students like the Internet very much. They often go into the Internet as soon as they are free. They make friends on the Internet and maybe they have never seen these friends. They don’t know their real names, ages, and even sex. They are so interested in making the “unreal friends” that they can’t put their hearts into study. Many of them can’t catch up with others on many subjects because of that.
We can use computers and the Internet to learn more about the world. But at the same time, we should remember that not all the things can be done by computers and the Internet.
1. The Internet can not be used for______.
A. studying B. shopping C. thinking D. playing
2. When the computer was invented, it was______.

A. It is wonderful B. It can make students study harder
C. It is not good for students D. It is helpful, but we can’t do everything on it.
