答案 ,,所以设,,,;;而;.故答案为:.根据条件便可设x=2k1+1,y=4k2+1,k1,k2∈Z,这样便可得出x+y=2(k1+2k2+1),而k1+2k2+1是整数,也就是x+y符合集合M的条件,这便得出x+y∈M.相关推荐 1下列集合中与集合不相等的是( ) A.B. C.D. 2已知集合,,,若,,则x+y___M.(用“”或“...

【解析】(1)三方程左右两边相加得:2(a+b+c)=6,a+b+c=3,又∵k=a+b+c∴k=3 ,把k=3代入y=kx-k得:y=3x-3.(2)y=3x-3.∴当x=0时,y=-3;当y=0时,x=1;∴OA=1 , OB=3AB=12+32-=10-√3=1【两条直线平行】当两个一次函数表达式中的k相同,b若直线1=k1x+b与直线y2=k2x...

【答案】1 k1 2【解析】此题考查了解二元一次方程组,以及解一元一次不等式组,将方程组两方程相减表示出(x﹣y)是解本题的关键.方程组两方程相减表示出x﹣y,根据﹣1<x﹣y<0列出关于k的不等式,求出不等式的解集即可求出k的范围.解:x+2y=4k① 2x+y=2k+1②由②﹣①,得x﹣y=1﹣2k.∵﹣1<x﹣y...
In the PIN184 population, genome wide association analysis of SolCAP SNPs was performed using the kinship model K1 (a mixed linear model) described in Mosquera et al. [36]. The kinship matrix was calculated based on the genotypes of 241 SolCAP SNPs that were selected for equal distribution ...
三阶行列式|(array)l4&2&k(-3)&5&4(-5)&1&(-2)(array)|中第2行第1列的元素-3的代数余子式为(-1)^(2+1)|(array)l2&k1&(-2)(array)|=4+k,故4+k=-10,解得k=-14.故答案为:-14.结果一 题目 (3分)三阶行列式42k-354-11-2第2行第1列元素的代数余子式为10,则k= ....
The design and performance of a 16*16 bit parallel multiplier based on a 6 K gate array will be presented. This LSI semicustom IC demonstrates the high potential of the authors' AlGaAs/GaAs quantum well FETs with a gate length of 0.3 mu m. The best multiplication time measured was 7.2 ...
