This can be modelled as an inequality:
Profit > costs
Let x be the number of books, so:
15x > 4x + 3500
11x > 3500
x > 3500 / 11
x > 318.18
so you need to sell 319 books.
Hope that helped!
For this equationThe answer to be -3 -.5 and two because that is where the points are touching the X axis
We are given the equation that is an inequality, y>x^2-6x+7. In this problem, we are asked to determine points that correctly coincide with the graph. In this case, all we have to do is to substitute x with the number and check whether the answer is less than y. If that is the case, that is the correct answer.
The answer is B and I’m really sure about it
