Question 106436: I really love how you all take the time to help us students. Thank you all once again. I sent in a graphing question but waiting on the answer, but have a similar one here as well. I need to be able to graph these four feasible regions of the system: (a) x ≤ (1/2) y, x + y ≤ 1000, x ≥ 0, y ≥ 0 . Some of the problems I am having are that even if I do find an on-line calculator, I am also unable to copy it by right clicking. The two main problems are being able to copy graph and finding the right calculator(s). Can you help me with this problem please?

Question 106533: My instructor want us to write linear inequalities for this information: A formula for a special blend of nuts used to make large batches of cookie dough. Cost of this blend:
$6 per lb. of nuts to be mixed with
$5 per lb. of nuts to get a total of
at least 50 lbs of blended nuts.
I can list the variables as $6 lb. = (a), $5 lb. = (b), and 50 lbs = (c). This is how I see the variable, but I could be wrong. I just do not know how to take this information and write linear inequalities. Can you help please? Thank you in advance incase I do not receive an email.

Question 107735: Word problem
If an inventor charges $4 per unit, the profit for producing and selling x units is given by the function p(x) = 2.25x - 7000
a. What is her profit if she sells 2000 units?
p(2000)= 2.25(2000) - 7000
p(2000) = 4500 - 7000
p(2000)= -2500
Am I on the right track for this type of problem?
