12.How many ordered pairs of real numbers (T, ) satisfy the following system of equations?x+3y=3||x|-|y||=1 有多少个有序实数对(x,y)满足下面的方程组x+3y=3||x|-|y||=1 (A)1 (B)2(C)3 (D)4 (E)8 相关知识点: 试题来源: 解析 答案C 解析 一由3+3y=3得:
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 ...
Substitute into the same equation your original value for m. For example, your original value for m was -1.25. Write, y = -1.25x + 10.75. You have calculated a function from the ordered pairs (3,7) and (7,2). Things Needed Paper Pencil Calculator Woloch, John. "How To Calculate Fu...
