You can put this solution on YOUR website! I can't solve or graph this. Please help.
5-4x≥17 and 6x-4>44
The first ">" should be underlined in the equation.
..
The rules for solving inequalities are the same as those used for solving regular equations except for one important rule, that is, when you multiply both sides of an inequality by -1, the inequality sign reverses.
..
5-4x≥17
-4x≥12
-x≥3
x≤3
..
6x-4>44
6x>48
x>8
..
solution in interval notation:
(-∞,3] U (8,∞)
..
I don't have the means to graph it for you, but I can describe how you should do it. Draw one solid vertical line at x=3, and another dashed vertical line at x=8. Shade to the right of x=8 and shade to the left of x=3. The solid and dashed lines indicate including or not including the x-value.
