I believe that the answer is D because domain values are the x-coordinates and there are two -1 x-values that have different ranges (y-values)
Answer:
Step-by-step explanation:
Let c represent the number of child tickets that were sold.
Let a represent the number of adult tickets that were sold.
The Celluloid Cinema sold 150 tickets to a movie. This means that
a + c = 150
A child ticket cost $7.75 and an adult ticket cost $10.25. If the cinema sold $1470 worth of tickets, it means that
10.25a + 7.75c = 1470
Therefore, the system of equations that could be used to determine how many adult tickets, a, and how many child tickets c were sold is
1) a + c = 150
10.25a + 7.75c = 1470
Option 2 is incorrect because a + c is not equal to 1470
Option 3 is incorrect because rate of child and adult tickets were interchanged.
Option 4 is incorrect because a + c is not equal to 1470 and the rate of child and adult tickets were interchanged.
Answer:
-6
