This >= is greater than and equal to and this <= is less than and equal to
6. 7+x>=9
So first you would subtract the 7 from both sides to isolate x
7+x>=9
-7 -7
x>=2 You then draw a circle on 2 on the number line and shade it in since it is supposed to equal to 2 and make the line go to the right since it's greater than.
8. 0>=x+12
Subtract the 12 to the other side to get the x alone
-12>=x
flip the equation the other way so the x is on the other side so you don't get confused when putting it on the number line
x<=-12
You then circle the -12 on the number line and shade it in since it is supposed to equal to 12 also and make the line go to the left since it's less than.
10. 13+x>=13
Subtract the 13 to the other side to get the x alone
13+x>=13
-13 -13
x>=0
You then circle the 0 on the number line and shade it in since it is supposed to equal to 0 and make the line go to the right since it's greater than.
