C=65
If its wrong I’m really sorry:(
D is a function because there are no repeated x values
for example b is not a function because we have (0,-7) and (0,-9)
Here, x - y = 2342
x = 2342 + y
Substitute this value into first equation,
2342 + y + y = 3500
2y = 3500 - 2342
y = 1158/2
y = 579
So, x = 2342 + 579 = 2921
In short, Your Answer would be 2921 contemporary titles
Hope this helps!
The answer would be 11x-12
