The correct answer is B (2,1)
Max is 26 now because 24 + 2 = 26 so 26 / 2 = 13
Liam is 13.
I hope this helps :)
Joint variation means that w=kxy where k is constant.
Finding k:
12=k*2*18
12=36k
k=1/3
Now plug in second set of values
16= 1/3*6*y
16=2*y
y=8
Final answer: 8
The correct answer is x= -9. Hope this helps!!
