2008-2009初一年级期中考试
数学试卷答案
一、1、 2、10-mn 3、-5 4、-1,2 5、五,三 6、3
7、3x3y+x2y2- xy3 +y4 8、0,2 9、-3a2+3a-2 10、-a6
11、-x8 12、-8a3 13、-2x3-x2+2x 14、4b2-a2 15、216-1
二、16、D 17、B 18、B 19、D
三、20、原式= x+ +5 (1’)
= x+ +5 (1’)
= x+ +5 (1’)
= x+4x-3y+5 (1’)
= 5x-3y+5 (2’)
21、原式=(x2-4)(x2+4)-(x4-4x2+4) (1’)
= x4-16-x4+4x2-4 (1’)
= 4x2-20 (1’)
当x = 时,原式的值= 4×( )2-20 (1’)
= 4× -20 (1’)
=-19 (1’)
22、原式=x2-2x+1+x2-9+x2-4x+3 (1’)
=3x2-6x-5 (1’)
=3(x2-2x)-5 (2’) (或者由x2-2x=2得3x2-6x=6代入也可)
=3×2-5 (1’)
=1 (1’)
23、 A-2B = x-1
2B = A-(x-1) (1’)
2B = 2x2-x+1-(x-1) (1’)
2B = 2x2-x+1-x+1 (1’)
2B = 2x2-2x+2 (1’)
B = x2-x+1 (2’)
24、(1) (2’)
(2) (2’)
(3) + - - = (3’)
25、(1)C2 = C 2-2ab (3’)
(2)(b-a)2或者b 2-2ab+a 2 (3’)
(3)C 2= a 2+b 2 (1’)
26、(25)2 = a2 (1’)
a = 32 (1’)
210 = 22b (1’)
b = 5 (1’)
原式=( a)2- ( b) 2-( a2+ ab+ b2) (1’)
= a2- b2- a2- ab- b2 (1’)
=- ab- b2 (1’)
当a = 32,b = 5时,原式的值= - ×32×5- ×52 = -18 (1’)
若直接代入:(8+1)(8-1)-(8+1)2 = -18也可以.
27、解(1):第一小队送给第二小队共(m+2)•m件 (2’)
第二小队送给第一小队共m•(m+2)件 (2’)
两队共赠送2m•(m+2)件 (2’)
(2):当m = 2×102+4×10=240 件 (2’)
28、设:1997年商品价格为x元 (1’)
1998年商品价格为(1+5%)x元 (1’)
1999年商品价格为(1+5%)(1+10%)x元 (1’)
2000年商品价格为(1+5%)(1+10%)(1-12%)x元=1.0164x元 (2’)
=0.0164=1.64% (2’)
答:2000年比1997年涨价1.64%. (1’)
