Write an inequality for the following problem:
You spend $46 on supplies to make ornaments and plan to sell them for $8.50 each. How many do you need to sell to have a positive profit?
(use x as your variable and no spaces)
Decide if the inequality has a solution, no solution, or all solutions:
8x - 3 > -5
Decide if the inequality has a solution, no solution, or all solutions:
3y - 5 > 2y - 7 + y
Decide if the inequality has a solution, no solution, or all solutions:
3(x - 2) > 4x - 6
Decide if the inequality has a solution, no solution, or all solutions:
6(x + 3) < 7x + 18 - x
Refer to problem #5.
What is the least number of ornaments you can sell for your profit to be positive?
For which values of a and b are all the solutions of ax+b > 0 positive?
