Sometimes I can figure them out, and sometimes I'm having HUGE problems like these two questions, who are actually pretty easy, but for some reasons I also keep getting the wrong answers, like I never get the answers who are listed for the question. It's like. ugh.\r

Algebra.Com's Answer #501292 by mananth(16946)![]() ![]() You can put this solution on YOUR website! If the coordinates of A and B are ( x1, y1) and ( x2, y2) respectively, then the midpoint, M, of AB is given by the following formula \n" ); document.write( "( 1 , 8 ) ( -5 , 10 ) \n" ); document.write( "M(x,y) = \n" ); document.write( " \n" ); document.write( "x= -2 ,y= 9 \n" ); document.write( "-------------\r \n" ); document.write( "\n" ); document.write( "P(x,y) = \n" ); document.write( "\n" ); document.write( "P(x,y)=(2,5) \n" ); document.write( "M=(0,7)\r \n" ); document.write( "\n" ); document.write( "2=(x1+2)/2 \n" ); document.write( "4=x1+2 \n" ); document.write( "x1=4-2 \n" ); document.write( "x1=2\r \n" ); document.write( "\n" ); document.write( "5= y1+7)/2 \n" ); document.write( "10=y1+7 \n" ); document.write( "y1=10-7 \n" ); document.write( "y1=3\r \n" ); document.write( "\n" ); document.write( "G=(2,3) \n" ); document.write( " |
