[精品]一家银行的信贷部计划年初投入25

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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
