i believe the formula you need is; SA= n(3/10 ib) + 9b
Answer: Ix - 5I ≥ 5.
Step-by-step explanation:
We want the set:
[0, 10]
to be the solution of:
Ix - bI ≤ c
So we need to find the values of c and b.
The first step is to find the middle point in our segment.
We can do that by adding the extremes and dividing it by 2.
M = (10 + 0)/2 = 5
And we also want to find half of the difference between the extremes, this is:
D = (10 - 0)/2 = 5.
Now, this set will be the set of solutions of:
Ix - MI ≥ D
Then in our case, we have:
Ix - 5I ≥ 5.
so we have that b = 5, and c = 5.
For the first one t could be a volcano that’s slowly caving in over time, and for the 2nd one it could be a store that’s selling something, and the cost per person was bigger when there was less people, but since more people came they didn’t have to charge as much ^ ^
