After h hours A has 6000 - 2000h cells and B has 2000 - 1000h. Equating them as one form:
6000 - 2000h = 2000 - 1000h
-2000h + 1000h = 2000 - 6000
-1000h = -4000
h = -4000/-1000 = 4 hours
Answer:
x=3, y=5
Step-by-step explanation:
One such polynomial might be

Another with the same roots would be
The sequence is to multiply by -3. Therefore, you want to multiply by -3 which gives you 108. Since it is a negative by a positive the answer would be negative. The next term would be -108.
14-6=p
Or: 6+p=14
One of those should work :)
The answer is 8.
