Algebra.Com's Answer #299096 by stanbon(75887) ![]() You can put this solution on YOUR website! I have been given a single line graph that essentially states -12 > x <= 4 (line graph is drawn) \n" ); document.write( "------------------------------------------- \n" ); document.write( "Comment: -12 > x <=4 is a meaningless inequality. \n" ); document.write( "It says -12 is greater than 4; that is not true. \n" ); document.write( "Did you post the problem correctly? \n" ); document.write( "Maybe you meant -12 < x <=4. \n" ); document.write( "--- \n" ); document.write( "If you did you would proceed as follows: \n" ); document.write( "Multiply thru by 3 to get: \n" ); document.write( "-36 < 3x <= 12 \n" ); document.write( "Subtracting 4 you would get: \n" ); document.write( "-40 < 3x-4 <= 8 \n" ); document.write( "===================== \n" ); document.write( "But none of the answers below says that. \n" ); document.write( "======================== \n" ); document.write( "Hmmmm????? \n" ); document.write( "============= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H.\r \n" ); document.write( "\n" ); document.write( "The question then is: which inequality illustrates the graph. \n" ); document.write( "a. -3x+4>=-8 \n" ); document.write( "b. 3x-4>=8 \n" ); document.write( "c. -3x-4>=8 \n" ); document.write( "d. none of these \n" ); document.write( " \n" ); document.write( " |
