Hi,

I need help solving this first-order differential equation: dy/dx = e^4x(y-3). Could you explain how this would be seperated in order to solve it?

Hi, this question was in a year 11 extension maths textbook in the enrichment section. I have the answer as k>17 and k<-11 because I graphed it on GeoGebra. The Graph can be found here: https://ggbm.at/xpegwwtq. While I know the answers I would like to know how to work it out using algebra.

Here is the Question:
Consider the cubic equation x^3 - kx + (k + 11) = 0, find all the integer values of k for which the equation has at least one positive integer solution for x

Thanks, Taran

cant seem to get the correct answer I know the steps on this worded problem I am working on. What I am in need of if the steps so far are right or wrong in solving it.  it is in two parts. Heres the problem

2. Maria Rios sells commercial restaurant supplies and equipment. She is paid on a commission-only basis. Shereceives 2% for her sales up to $60,000. For the next $90,000 of sales, she is paid 3%, and for any sales above$150,000 she is paid 4%. How much commission would Maria earn in a month when her sales were$195,000?

3. Maria Rios (problem 2) is not paid commission on any restaurant supplies or equipment that are later returned.If an item is returned, its price is deducted from Maria’s total sales to get her net sales. The commission-onlyrate is applied to her net sales. Suppose that Maria sold merchandise worth $195,000 but that $40,000 of thatwas later returned.What would be Maria’s commission on net sa
