I was going to answer you, but then I tripped so I couldn't. Just kidding. The square root of 8 is a constant. It does not change as x changes. Therefore the graph would look like a line rather than a square root curve. In order for the function to be a square root functio...

Well, what sort of help do you need? You'll need to post a homework question, show your work, and explain where you are getting stuck.

Math help, anyone?
On the internet, look up what a right triangle is. Then, come back to this website and tell me what a right triangle is. From there, we can continue to answer your original question.

Math help, anyone?
Well to start, do you know what a right triangle is?

Yes, you are correct. Well done.

Math
What do you think? Do you have any thoughts on this? If you had to guess, what would be your answer, and why?

Algebra 1
Yes, you are correct. $50 must be greater than the total cost of 0.12m + $20 Good job.

Algebra 1
The answer is not D. $50 must be greater than the total cost. If the answer were D, then this would imply that $50 is less than the total cost.

tech
The phrase "responsibility for intellectual property" is vague. Social networks make users responsible for ensuring that they (the users) have permission to upload whatever they are uploading.

Tech
Yes, the best answer is D. However, it is worth nothing that many people have been sued (successfully) for stealing ideas.

Tech E.D
Again, the term "copyrighted" is vague. Damon's answer is precisely correct. However, I'm afraid there is a good chance that the answer your textbook or teacher is looking for is B. ideas.
