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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
