Algebra.Com's Answer #147995 by Mathtut(3670)![]() ![]() ![]() You can put this solution on YOUR website! then the problem reads that 2x+3 is greater than or equal to -15 \n" ); document.write( ": \n" ); document.write( "2x>-18.....subtracted 3 from both sides \n" ); document.write( ": \n" ); document.write( "x>-9.......divided both sides by 2 \n" ); document.write( ": \n" ); document.write( "since this is greater than or equal to means that the boundry line is solid because it is included \n" ); document.write( ": \n" ); document.write( "the boundry line is a solid line at x=-9......the shade portion will be that portion which makes our inequality true...do a test point on each side. \n" ); document.write( ": \n" ); document.write( "(-10,0) is on the left side and (0,0) is on the right \n" ); document.write( ": \n" ); document.write( "-10>-9........is not false \n" ); document.write( "0>-9 .........is true \n" ); document.write( ": \n" ); document.write( "therefore our boundry line is x=-9 which is a line 9 units to the left and parallel to the y axis. the shade portion is everything to the right of this line \n" ); document.write( " |
