Answer:
2.5
Step-by-step explanation:
The minimum value is the minimum y-value a function includes. In this case, since you can see the function is periodic (it repeats itself <em>periodically</em>, hence periodic) and the smallest y-value the function encounters is 2.5 (doesn't go below this value), the minimum y-value is 2.5. I hope this made sense. If not, feel free to let me know.
This is incorrect
-a = b
a + c = d
b + c = d is incorrect because it says a + c and not -a + c.
If you multiply the first line with -1 then you would get a = -b
So the final line would actually be -b+c=d
Answer:

Step-by-step explanation:
Let's start by turning 8 1/2 into an improper fraction, which would be 17/2. To find the amount of cups needed for a cake that is 3/4 of a full cake, we multiply 17/2 by 3/4.

Turn the fraction into a mixed number:

That should be the correct answer. Hope this helps!!!
If the diameter is 18, the radius would be nine. Someone please tell me if I missed something.
