Algebra.Com's Answer #659374 by jim_thompson5910(35256)![]() ![]() ![]() You can put this solution on YOUR website! Let x be an element in set C. Since x is in set C, it must be in BOTH set A and in set B because C is a subset of the intersection of A and B.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "If you draw a venn diagram, the region where A and B overlap is where set C will be. Set C will either be the whole overlapping region or a smaller region inside this overlap. \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So this means that if x is in C, then x is in A. Also, x is in B. The element x is a general representative of any element in set C. So that means if C is a subset of A intersect B, then C is a subset of A and C is a subset of B \n" ); document.write( " \n" ); document.write( " |
