8 - (2/x) = y (ignore these words the answer was too short lol)
Answer:
x > 3
Step-by-step explanation:
-2(x-5) < 4
-2x+10 < 4
-2x < -6
x > 3
So here we just are gonna distribute and simplify.
After first week pond will be:
10 + 10* 0.03 = 10*(1.03) feet deep
after second week it will be:
10*(1.03) + 10*(1.03)*0.03 = 10*(1.03)^2
from this we can conclude that after x week its will be:
10*(1.03)^x
Note that when second week starts our starting pond is already greater by 3%. every week we add 3% of prevous weeks size of pond
for x = 8 we get
f(x) = 10*(1.03)^8 = 12.66 or rounded 13 feet
Answer is D.
