Choose the correct description of the graph of the inequality x - 3 >= 5. A. Open circle on 8, shading to the left. B. Closed circle on 8, shading to the left. C. Open circle on 8, shading to the right. D. Closed circle on 8, shading to the right. I think its D, am I right?

OpenStudy (anonymous):

Yes it is D. Here is the diagram to show(excludes circle) http://www.wolframalpha.com/input/?i=x+-+3+%3E%3D+5

Choose the correct description of the graph of the inequality -2x > 10. A. Open circle on -5, shading to the left. B. Closed circle on -5, shading to the left. C. Open circle on -5, shading to the right. D. Closed circle on -5, shading to the right.

I think this one is A?

OpenStudy (anonymous):

Right you are again Here is proof: http://www.wolframalpha.com/input/?i=-2x+%3E+10

thank you, I mite have some more questions so you will probably be seeing me a lot today, lol :)

Like this one, Solve the inequality 6x - 8 > 4x + 26. A. x < 9 B. x < 17 C. x > 9 D. x > 17 I'm having trouble with this one, how do I solve it?

OpenStudy (anonymous):

is it D?

OpenStudy (anonymous):

yup

Choose the missing step in the given solution to the inequality -x - 10 > 15 - 2x. First step: -x - 10 > 15 - 2x Second step:-10 > 15 - x Final step: 25 < x A. -25 > -x B. -25 < -x C. 25 > x D. 25 < x I think this one is B?
