State the solution set in interval notation and sketch its graph.
\n" ); document.write( "#114
\n" ); document.write( "-3/8<= -1/4x + 1/8 < 5/8
\n" ); document.write( "Multiply thru by 8 to get:
\n" ); document.write( "-3 <= -2x+1 < 5
\n" ); document.write( "Subtract 1 along the line to get:
\n" ); document.write( "-4 <= -2x < 4
\n" ); document.write( "Divie thru by -2 to get:
\n" ); document.write( "-2 < x <= 2
\n" ); document.write( "-----------------
\n" ); document.write( "Draw a number line and mark the points -2 and 2
\n" ); document.write( "Draw an open circle at x=-2; Draw a solid circle at x=2
\n" ); document.write( "Draw a solid line segment connecting -2 and +2
\n" ); document.write( "That is the graph
