C
x + y = 210
3.5x + 6y = 935
Step-by-step explanation:
y = No. of students
x = No. of teachers
Total No. of people who attended the dinner = x + y = 210 (eq. 1)
Amount of tickets collected from all students = 6y
Amount of tickets collected from all teachers = 3.5x
Total amount collected from students= 3.5x + 6y = 935 (eq. 2)
Therefore:
x + y = 210
3.5x + 6y = 935

Separate each terms.
The domain for this square root is x >= -1
The domain for this square root is x <= 3
However.... the square root of 3 - x is the quotient. meaning that the quotient cannot be 0. Therefore the domain must be x < 3
Therefore the answer is D. - 1 <= x < 3
