Question 839578: I am not understanding I am on section 3.4 in math 105, my question is 2x+5y is greater or equal to 10. I have set them equal to 0 but when I graph it, it is telling me I am absolutely wrong this homework is due not tomorrow. I have been working all day on it I really need help.

You can put this solution on YOUR website!
"2x+5y is greater or equal to 10."

2x%2B5y%3E=10
-
Solve for y.
5y%3E=10-2x
5y%3E=-2x%2B10
highlight%28y%3E=-%282%2F5%29x%2B2%29

The solution will be the REGION above the line y=-(2/5)x+2, and including the line; you would draw a solid line for this graph if done on graph paper. Difficult to know exactly how to show this on the site system...

graph%28300%2C300%2C-10%2C10%2C-10%2C10%2Cy%3E=-2x%2F5%2B2%29
Again, the solution is ABOVE the line and INCLUDES the line. You would shade the region above the line.
