Let, the number = x
Then, x + 72/x = -17
x² + 72 = -17x
x² + 17x + 72 = 0
x² + 8x + 9x + 72 = 0
x(x + 8) 9(x + 8) = 0
(x + 8)(x + 9) = 0
x = -8 OR -9
In short, Your Number would be: Either -9 or -8
Hope this helps!
Answer:
The intersection point of the two curves is 
.
Step-by-step explanation:
From statement we get the following equations:
Supply curve
(1)
Demand curve
(2)
Where:
- Quantity, measured in thousands of metric tons.
- Price, measured in US dollars per metric tons.
If we add both equations, then we find that quantity is:
Then, we finally find the price by substituting on (2):
The intersection point of the two curves is .
