Someone please help me with this question and explain to me how to solve it

Okay so x greater then or equal to 7

To plot ask yourself:

Open or Closed Circle:

Open->, <

Closed-Greater then or equal to or less then or equal to

Also ask:

am i ploting to the left or to the right

Step-by-step explanation:

It is going to be a closed circle, since it is greater then or equal too

And you cand use the sign so it is going to go to the left < (that way)

You can use the sign to guied you ex: x>5 you are going to the right >

Also, for this topic just know if the equation is like this: 3>x

MAKE SURE TO SWICH IT TO THIS:

x<3

YOU HAVE TO SWITCH THE EQUATION AROUND AND THE SIGN

I hope this helped! :D
