Show Graph with the solution for 2x+3>-9
kicyunya [14]

Answer:

I can't graph on this but x > -6

To graph you should draw a vertical (up and down) dotted line, and shade the graph to the right of the line.

Step-by-step explanation:

2x+3>-9    Subtract 3 from both sides of the inequality.

2x> -12      Divide both sides by 2

x> -6
