5＝2.5×10﹣6；故选：C．7．【解答】解：由题意，得1﹣x≥0且x≠0，解得x≤1且x≠0，故选：D．8．【解答】解：在y＝﹣2x+3中，令y＝0可求得x＝1.5，令x＝0可得y＝3，∴函数与x轴交点坐标为（1.5，0），与y轴的交点坐标为（0，3），∴函数图象经过第一、二、四象限，故A不正确、B正确；∵﹣2＜0，∴y随x的增大而减小，故C不正确；当x＝1时，y＝1≠2，∴点（1，2）不在函数图象上，故D不正确；故选：B．9．【解答】解：过线段AB中点作AB的垂直平分线，如图，∵在x轴或y轴上有一点P，且点P到点A和点B的距离相等，∴P点坐标为（1，0）或（0，﹣1）故选：A．10．【解答】解：若卡片每张x元，笔每支y元，由题意得：，故选：B．11．【解答】解：中间一项为加上或减去x和2积的2倍，故m＝±4，故填±4．12．【解答】解：∵函数y＝2x+k﹣4是正比例函数，∴k﹣4＝0，解得：k＝4．故答案为：4．13．【解答】解：根据题意画图如下：共有12种等可能的结果数，其中第1小组和第2小组被抽到的有2种，则第1小组和第2小组被抽到的概率是＝；故答案为：．14．【解答】解：设直线AB的解析式为y＝﹣x+b．将（0，﹣4）代入得b＝﹣4，∴直线AB的解析式为y＝﹣x﹣4．∴A（﹣8，0），∴AB＝＝4故答案为y＝﹣x﹣4，4．15．【解答】解：（1）﹣3﹣＝2﹣3×+3＝2﹣+3＝+3；（2）﹣a2b+（3ab2﹣a2b）﹣2（2ab2﹣a2b）＝﹣a2b+3ab2﹣a2b﹣4ab2+2a2b＝﹣ab2，当a＝﹣1，b＝﹣2时，原式＝﹣（﹣1）×（﹣2）2＝4．16．【解答】解：方程组整理得：，①×2﹣②得：3y＝9，解得y＝3，把y＝3代入①得：x+6＝11，解得x＝5，所以方程组的解为：．17．【解答】解：∵EF∥CD，∴∠E＝∠DCB＝35°，∵CD平分∠ACB，∴∠ACB＝2∠DCB＝70°，∵∠B＝60°，∴∠A＝180°﹣60°﹣70°＝50°．18．【解答】解：（1）由题意可得总人数为10÷20%＝50名，扇形统计图中的B所对应的圆心角度数是360°×＝36°，故答案为：50、36；（2）听音乐的人数为50﹣10﹣15﹣5﹣8＝12名，补全统计图得：（3）从被调查的学生中随机选择一个同学，他选择的减压方式是“体育活动”的概率是＝，故答案为：．19．【解答】解：（1）该城市会受到这次台风的影响．理由是：如图，过A作AD⊥BC于D．在Rt△ABD中，∵∠ABD＝30°，AB＝240，∴AD＝AB＝120，∵城市受到的风力达到或超过四级，则称受台风影响，∴受台风影响范围的半径为25×（12﹣4）＝200．∵120＜200，∴该城市会受到这次台风的影响．（2）如图以A为圆心，200为半径作⊙A交BC于E、F．则AE＝AF＝200．∴台风影响该市持续的路程为：EF＝2DE＝2＝320．∴台风影响该市的持续时间t＝320÷20＝16（小时）．（3）∵AD距台风中心最近，∴该城市受到这次台风最大风力为：12﹣（120÷25）＝7.2（级）．20．【解答】解：（1）∵AE⊥PB，CF⊥BP，∴∠AEO＝∠CFO＝90°，在△AEO和△CFO中，，∴△AOE≌△COF（AAS），∴OE＝OF；（2）①图2中的结论为：CF＝OE+AE，证明如下：延长EO交CF于点G，∵AE⊥BP，CF⊥BP，∴AE∥CF，∴∠EAO＝∠GCO，在△EOA和△GOC中，，∴△EOA≌△GOC（ASA），∴EO＝GO，AE＝CG，在Rt△EFG中，∵EO＝OG，∴OE＝OF＝GO，∵∠OFE＝30°，∴∠OFG＝90°﹣30°＝60°，∴△OFG是等边三角形，∴OF＝GF，∵OE＝OF，∴OE＝FG，∵CF＝FG+CG，∴CF＝OE+AE．②图3的结论CF＝OE﹣AE，证明如下：延长EO交FC的延长线于点G，∵AE⊥BP，CF⊥BP，∴AE∥CF，∴∠AEO＝∠G，在△AOE和△COG中，，∴△AOE≌△COG（AAS），∴OE＝OG，AE＝CG，在Rt△EFG中，∵OE＝OG，∴OE＝OF＝OG，∵∠OFE＝30°，∴∠OFG＝90°﹣30°＝60°，∴△OFG是等边三角形，∴OF＝FG，∵OE＝OF，∴OE＝FG，∵CF＝FG﹣CG，∴CF＝OE﹣AE．21．【解答】解：∵x＝2+，y＝2﹣，∴x+y＝4，xy＝1，则原式＝（x+y）2﹣xy＝16﹣1＝15，故答案为：1522．【解答】解：∵x＝，∴4x2+4x﹣2017＝（2x+1）2﹣2018＝＝＝＝3﹣2018＝﹣2015．故答案为；﹣2015．23．【解答】解：∵点P（1，）在“勾股一次函数”y＝的图象上，∴，即a+b＝，又∵a，b，c分别是Rt△ABC的三条变长，∠C＝90°，Rt△ABC的面积是5，∴ab＝5，即ab＝10，又∵a2+b2＝c2，∴（a+b）2﹣2ab＝c2，即∴（）2﹣2×10＝c2，解得c＝5，故答案为：5．24．【解答】解：当x＝0，y＝4，当y＝0时，﹣x+4＝0，x＝4，∴OE＝OF＝4，∴△EOF是等腰直角三角形，∴∠C1EF＝45°∴△B1C1E是等腰直角三角形，∴B1C1＝EC1，∵四边形OA1B1C1为正方形，∴OC1＝C1B1＝EC1＝2，∴B1（2，2），A1（2，0），同理可得：C2是A1B1的中点，∴B2（2+1＝3，1），A2（3，0），B3（2+1+＝，），A3（，0），B4（+＝，），A4（，0），B5（+＝，）．故答案为：（，0），（，）．25．【解答】解：∵AC＝BC，∠BCA＝120°∴∠CAB＝∠CBA＝30°∵△CAD与△CBD分别沿直线CA、CB翻折得到△CAP与△CBQ∴AD＝AP，PC＝DC，∠PAC＝∠CAD＝30°，BD＝BQ，CD＝CQ，∠QBC＝∠CBD＝30°∴CP＝CQ＝CD 故①正确AC垂直平分PD，故②正确∠PAD＝∠QBD＝60°，且PA＝AD，BQ＝BD∴△APD，△QBD都是等边三角形∴∠PDA＝∠QDB＝60°∴∠PDQ＝60°∵CP＝CQ＝CD∴∠PDC＝∠CPD，∠CPQ＝∠CQP，∠CDQ＝∠CQD∵∠PDC+CDQ＝60°∴∠CPQ+∠CQP＝180﹣2×60＝60°∴∠CPQ＝30°即∠CPQ是定值故③错误当D是AB的中点，且CA＝CB∴AD＝BD且△APD，△QBD都是等边三角形∴PD＝DQ且∠PDQ＝60°∴△PDQ是等边三角形．故④正确故答案为①②④26．【解答】解：（1）∵当x＝0时，y＝600，∴甲乙两地相距600千米．600÷10＝60（千米/小时）．故答案为：600；60．（2）设快车的速度为a千米/小时，根据题意得：4（60+a）＝600，解得：a＝90．答：快车速度是90千米/小时．（3）快车到达甲地的时间为600÷90＝（小时），当x＝时，两车之间的距离为60×＝400（千米）．设当4≤x≤时，y与x之间的函数关系式为y＝kx+b（k≠0），∵该函数图象经过点（4，0）和（，400），∴，解得：，∴从两车相遇到快车到达甲地时y与x之间的函数关系式为y＝150x﹣600．（4）设当0≤x≤4时，y与x之间的函数关系式为y＝mx+n（m≠0），∵该函数图象经过点（0，600）和（4，0），∴，解得：，∴y与x之间的函数关系式为y＝﹣150x+600．当y＝300时，有﹣150x+600＝300或150x﹣600＝300，解得：x＝2或x＝6．∴当x＝2小时或x＝6小时时，两车相距300千米．27．【解答】解：（1）△ABC的面积＝3×3﹣×2×1﹣×3×1﹣×2×3，＝9﹣1﹣1.5﹣3，＝9﹣5.5，＝3.5；（2）△DEF如图2所示；面积＝2×4﹣×1×2﹣×2×2﹣×1×4，＝8﹣1﹣2﹣2，＝8﹣5，＝3；（3）∵△ABE是等腰直角三角形，∴AB＝AE，∠BAE＝90°，∴∠PAE+∠BAG＝180°﹣90°＝90°，又∵∠AEP+∠PAE＝90°，∴∠BAG＝∠AEP，在△ABG和△EAP中，，∴△ABG≌△EAP（AAS），同理可证，△ACG≌△FAQ，∴EP＝AG＝FQ；（4）如图4，过R作RH⊥PQ于H，设RH＝h，在Rt△PRH中，PH＝＝，在Rt△RQH中，QH＝＝，∴PQ＝+＝6，＝6﹣，两边平方得，25﹣h2＝36﹣12+13﹣h2，整理得，＝2，两边平方得，13﹣h2＝4，解得h＝3，∴S△PQR＝×6×3＝9，∴六边形花坛ABCDEF的面积＝25+13+36+4×9＝74+36＝110m2．故答案为：（1）3.5；（2）3；（4）110．28．【解答】解：（1）把点A（﹣6，0）代入，得m＝8，∴点B坐标为（0，8）．（2）存在，设点C坐标为（0，b），∴BC＝|8﹣b|，∴×6×|8﹣b|＝12，解得b＝4或12，∴点C坐标（0，12）或（0，4）．（3）如图1中，①当AB＝AP时，AP＝AB＝＝10，可得P1（﹣16，0），P2（4，0）．②当BA＝BP时，OA＝OP，可得P3（6，0）．③当PA＝PB时，∵线段AB的垂直平分线为y＝﹣x+，可得P4（，0），综上所述，满足条件的点P坐标为（﹣16，0）或（4，0）或（6，0）或（，0）。
