一家银行的信贷部计划年初投入25【精品-ppt】

一家银行的信贷部计划年初投入25000000元用于企业投资和个人贷款，希望这笔资金至少可带来30000元的收益，其中从企业贷款中获益12，从个人贷款中获益10，那么，信贷部应该如何分配资金呢则分配资金应该满足的条件为复习怎么样表示现实生活中存在的一些不等关系二元一次不等式组创设情境分析假设信贷部用于企业投资的资金为X元，用于个人贷款为Y元回忆初中一元一次不等式（组）的解集如何表示思考在直角坐标系内，二元一次不等式（组）的解集又如何表示呢例如温故知新探讨在平面内画一条直线，这条直线将平面分为几个部分这几个部分可以用怎样的式子来表示在平面直角坐标系中，所有的点被直线分成三类在直线上；在直线的左下方的平面区域内；在直线的右上方的平面区域内。新知探究66对于平面上坐标为3,3（0,0）,2,3,7,0,1,6的点讨论它们分别在直线的什么方位,它们的值分别为什么7,03,32,31,6（0,0）新知探究XY（1）二元一次不等式AXBYC0A,B不全为0在平面直角坐标系中表示直线AXBYC0某一侧所有点组成的平面区域。（2）由于对直线同一侧的所有点X,Y，把它代入AXBYC，所得实数的符号都相同，所以只需在此直线的某一侧取一个特殊点X0,Y0，从AX0BY0C的正负可以判断出AXBYC0表示哪一侧的区域。注意新知探究小诀窍YXAXBYC0如果C0,可取0,0如果C0,可取1,0或0,1判断方法直线定界,特殊点定域归纳提升O新知探究例4、画出不等式2XY60在平面直角坐标系中表示直线AXBYC0某一侧所有点组成的平面区域。确定步骤直线定界，特殊点定域；若C0，则直线定界，原点定域；小结二元一次不等式AXBYC0在平面直角坐标系中表示直线AXBYC0某一侧所有点组成的平面区域。确定步骤直线定界，系数定域；课堂小结，根据所给图形，把图中的平面区域用不等式表示出来XY10探索提高YOX42XY0Y20X2Y402例6、用不等式（组）表示由三直线XY0X2Y40及Y20所围成的平面区域。探索提高XY0XY0XY0XY0XY0XY0XY0XY0XY00XYXY0XY0ABCDA探索提高二元一次不等式表示平面区域二元一次不等式表示哪个平面区域的判定方法系数法、特值法）二元一次不等式组表示平面区域每个二元一次不等式表示区域的公共部分数学思想数形结合、化归、分类讨论小结课后思考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
