Hey,
For example, how can one solve this inequality: 2x > -6 graphically using a coordinate system? I'm not really understanding it right now… Maybe someone can help me.
Best regards

Loading...Hello, my Casio Classpad 2 calculator has a fairly large crack, and apart from turning it on and off, nothing works anymore. Where can I get it repaired, and how much does it cost? Is there a warranty for the calculator? Thanks.
Hello, how do you calculate the vertices here? Because I have no idea how to calculate the vertices here and every time I calculate, the results are always wrong
Can anyone help me find the route AB? I'd be grateful for any answers.
If everything is relative…including information, can we rely on our knowledge?
If you want to describe the positional relationship between a plane and a straight line, it says that they can be truly parallel to each other, but what is the difference between parallel and truly parallel?
You plot the line y = 2x in a coordinate system and the constant -6 (a straight line at y = -6). Then you look for which x 2x is greater than -6. This is the case for all x > -3.
And don't forget to highlight the omitted section, for example, with color. This is important for distinguishing between > and =>.
All you need is a number line. Rewrite it for x, marking all the values that can be substituted for x so that the inequality holds.
