Algebra.Com's Answer #165537 by bakerrrr(1)![]() ![]() ![]() You can put this solution on YOUR website! -3x<-9 or 2x>6x-4. This is a disjunction.\r \n" ); document.write( "\n" ); document.write( "The first step is to solve the one on the left... \n" ); document.write( "so divide by three, to find x.\r \n" ); document.write( "\n" ); document.write( "-3x<-9 divide by three. X>3. The < sign switches to > because you are dividing by a negative number.\r \n" ); document.write( "\n" ); document.write( "The second one... 2x>6x-4. Subtract 6x from both sides. \n" ); document.write( "2x-6x=-4. So now there is -4x>-4. Divide and the answer is x<1.\r \n" ); document.write( "\n" ); document.write( "Then make a number line... and plot the two points. Using open circles. One on 3, with an arrow pointing towards all of the greater numbers, and an open circle on 1 with all of the numbers less than it. \n" ); document.write( " |
