That is a picture of the problem that I uploaded to the internet.

Answer 1

Hi, the answer is C then B. You solve it first and the answer gives you C. Then its B because X is equal to or greater than 2. Since it can also be equal to, the circle is shaded in.

Answer 2

C. {x|x>=2}, and B.

Answer 3

4x>=8 divide both sides by 4 to get x>=2 so the first answer is C

Since its greater its going to point to the right, the solid dot means greater/less  than or equal to, the empty dot means just greater/less than so the 2nd answer would be B

Answer 4

x would have to be 2 or greater

so the answer to the first one is C

and the colored in circle means that it can be that # as well

and the line has to go pass the 2 so the answer to the second is B

Answer 5

Divide both sides by four because you need to isolate the variable. You will then have x is more than or equal to 2. When you have a "more than equal to" answer, the dot is completely shaded in and you put the arrow from point 2 to the right direction because your answer is more than two. The answer is B.
