一、选择题：本题共10小题，每题3分，共30分。在每小题所给出的四个选项中，只有一个是正确的，请把正确的选项填入表格中。
题号12345678910
选项ACACDCCBAD
二、填空题：本题共5小题，每题3分，共15分。
11.k<0均可12.13.414.215.
三、解答题：本题共8小题，共55分。要写出必要的文字说明或演算步骤。
16.(5分)
解：
方程的两边同时乘以2x-1得
10-5=2(2x-1)
解得：x=3分
检验：当x=时2x-1=≠04分
∴x=是原方程的解5分
17.(6分)解：(1)根据题意得：随机地从盒子里抽取一张，抽到数字3的概率为;2分
(2)列表如下：
-1-234
-1---(-2，-1)(3，-1)(4，-1)
-2(-1，-2)---(3，-2)(4，-2)
3(-1，3)(-2，3)---(4，3)
4(-1，4)(-2，4)(3，4)---
4分
所有等可能的情况数有12种，其中在反比例图象上的点有2种，则P==6分
18.(7分)(1)∵AB‖CD
∴∠B=∠C
在△ABE和△DCF中
AB=CD，∠B=∠C，BE=CF
∴△ABE≌△DCF3分
(2)由(1)得AE=DF
∠AEB=∠DFC
又∵∠AEB+∠AEC=180°
∠DFC+∠BFD=180°
∴∠AEC=∠BFD
∴AE‖DF
又∵AE=DF
∴四边形AFDE为平行四边形7分
19.(7分)(1)x>1或x<-32分
(2)画出图象5分
由图象得：-3
20.(8分)(1)
CD总计
Ax吨(200-x)吨200吨
B(240-x)吨(60+x)吨300吨
总计240吨260吨500吨3分
(2)∴yA=20x+25(200-x)=-5x+5000(0≤x≤200)，
yB=15(240-x)+18(60+x)=3x+4680(0≤x≤200).6分
(不求自变量的取值范围的扣1分)
(3)设总费用为w则w=yA+yB=(-5x+5000)+(3x+4680)
=-2x+9680
∵w随x的增大而减小
∴当x=200时运费最省，为w=92808分
答：A村运往C冷库200吨，A村运往D冷库0吨，B村运往C冷库40吨，B村运往D冷库260吨时运费最省为9680元，
21.(10分)(1)PN与⊙O相切.
证明：连接ON，
则∠ONA=∠OAN，
∵PM=PN，∴∠PNM=∠PMN.
∵∠AMO=∠PMN，∴∠PNM=∠AMO.
∴∠PNO=∠PNM+∠ONA=∠AMO+∠ONA=90°.
即PN与⊙O相切.3分
(2)成立.
证明：连接ON，
则∠ONA=∠OAN，
∵PM=PN，∴∠PNM=∠PMN.
在Rt△AOM中，
∴∠OMA+∠OAM=90°，
∴∠PNM+∠ONA=90°.
∴∠PNO=180°-90°=90°.
即PN与⊙O相切.6分
(3)解：连接ON，由(2)可知∠ONP=90°.
∵∠AMO=15°，PM=PN，∴∠PNM=15°，∠OPN=30°，
∴∠PON=60°，∠AON=30°.
作NE⊥OD，垂足为点E，
则NE=ON?sin60°=1×=.
S阴影=S△AOC+S扇形AON-S△CON=OC?OA+×π×12?CO?NE
=×1×1+π-×1×=+π-.10分
22.(12分)
解：(1)∵抛物线y=-x2+mx+n经过点A(0，3)，B(2，3)
