Equations express relationships between variables and constants. The solutions to two-variable equations consist of two values, known as ordered pairs, and written as (a, b) where "a" and "b" are real-number constants. An equation can have an infinite number of ordered pairs that make the ...

首先:ordered pairs of positive integers 这里的有序是必须递增的么,就是说1,0不对0,1就对了?for how many ordered pairs of positive integers(x,y) is 2x+3y 答案 楼主理解有偏颇,所谓有序,只不过是(x,y)中一个在左,就是x一个在右,就是y而已.有序 就是有左右的顺序,而非大小顺序,这两个数,大...
还有一点是 positive integers正整数不是应该不包括0么? 相关知识点: 试题来源: 解析 不一定是递增的 ordered pair的意思是有序对 也就是说(1,0)和(0,1)不是一回事 相当于x对应第一个数,y对应第二个数 分析总结。 orderedpairsofpositiveintegers这里的有序是必须递增的么就是说10不对反馈 收藏 ...
