I'm trying to find what x is greater to or less than to put it on a graph
2007-06-10 15:00:35 · update #1
1) 2x -3 > 3x -10
-3 + 10 > 3x - 2x
7 > x
x < 7
2) -11x + 9 > (or equal to) -13x + 5
9 -5 > (or equal to) -13x + 11x
4 > (or equal to) -2x
4/ -2 < (or equal to) x
-2 < (or equal to) x
x > (or equal to) x
*remember when multiplying/ dividing by a neg. in an inequality equation, u have to change the inequality sign
first draw a dotted line x=7 (because it's only less than not less than and equal to) on the graph, then shade in the parts where x is less than 7 (ie. on the left side)
same for 2nd question, except draw a solid line
