Algebra.Com's Answer #592259 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! It is A. Here is why.\r \n" ); document.write( "\n" ); document.write( "Jane's number is x \n" ); document.write( "Multiply it by -2 = -2x \n" ); document.write( "Subtract 2 = -2x-2\r \n" ); document.write( "\n" ); document.write( "This is an inequality -2x-2 >6 \n" ); document.write( "Add 2 to both sides -2x>8 \n" ); document.write( "divide by 2 and reverse the inequality: x <-4\r \n" ); document.write( "\n" ); document.write( "Test with -5 \n" ); document.write( "Multiply by -2 =10 \n" ); document.write( "subtract 2=8 >6\r \n" ); document.write( "\n" ); document.write( "Key: divide or multiply by negative number, must reverse inequality.\r \n" ); document.write( "\n" ); document.write( "2<3 \n" ); document.write( "Multiply both by (-1) \n" ); document.write( "-2 is > than -3. You must change the inequality with division or multiplication by a negative number. \n" ); document.write( " |
