How would I answer this?

x ≥ -2 will have a closed circle on -2 and will be shaded to the right

Step-by-step explanation:

First you will need to determine what circle to use

Here our sign in x ≥ -2 is ≥ so we will need to use a closed circle

Then to determine which way you shade, just follow the direction that the inequality sign is "pointing"

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.
