Answer:
Option B.
Step-by-step explanation:
Remember that the profit is defined as the difference between the revenue and the cost.
So, having a profit y = 0 means that the woodworker did not win nor lose anything.
Then the zeros of the function, the values of x such that the graph intersects the x-axis, are the prices such that she does not win nor loss anything.
In the graph we can see that the zeros are at:
x = 15 (the first one)
x = 70 (the second one)
so the zeros are at x = 15 and x = 70, and these are the prices such that the profit is zero, so at these prices she does not make nor lose money.
The correct option is B.
5.50 goes into 60.50 13.50 times
Solution: (3x + 4y - 3z) x (3x + 4y + 3z)
The answer is the first choice.
I assume you're asking where it meets the y axis
In an equation the last number is the y intercept so I'm this case it would be 1
