Just combine like terms (:
A.
The second and first quadrant, because the hour and temperatures are unlikely to be negative numbers. All positive numbers for both X and Y values are in the second quadrant. If the hour is before noon, then the X value will venture into quadrant one. The diagram shows the quadrants in a graph.
B. For both the time and the temperature to be negative, and in quadrant four, you would have to be located in possibly Alaska or northern Canada. In such locations colder areas would be more likely to have negative temperatures and at times before 12.

Answer:
The cost per duck is $5.00 and $8.00 for chickens
Step-by-step explanation:
The equation would be like this:
50c + 30d = 550 (divide this by 10)
5c + 3d = 55
3d = 55 - 5c (multiply by 3)
9d = 165 - 15c
Next,
44c + 36d = 532 (divide this by 4)
11c + 9d = 133
11c + 165 - 15c = 133
11c - 15c = 133 - 165
-4c = -32 (divide by -4)
c = 8
Therefore, the cost of each chicken is $8.00
9d = 165 - 15c
9d = 165 - 15(8)
9d = 165 - 120
9d = 45 (divide by 9)
d = 5
