I have a test tomorrow and a question just like this is going to be on the test. Can someone please solve/explain it to me?A salesperson sells two models of vacuum cleaners. One sells for $200 each, and the other sells for $300 each. The salesperson has a weekly goal of at least $1800.a) write an inequality relating the revenue from the vacuum cleaners to the sales goal.b) graph the inequality.c) if the salesperson sold exactly two $300 models last week, how many $200 models did she have to sell to make her sales goal?
For increasing cubic binomials the final formula is as follows: (a + b) ^ 3 = a^3 + 3*a^2*b^a million + 3*a^a million*b^2 + b^3 on your case, a is x and b is -y^5 So (x - y^5)^3 = x^3 + 3*x^2*(-y^5)^a million + 3*x^a million*(-y^5)^2 + (-y^5)^3 Simplified: =x^3 - 3x^2*y^5 + 3x*y^10 - y^15 :D
