Answer:
Since i don't know what formula is mentioned. I just used the easiest way to solve :)
Step-by-step explanation:




Let h = the number of horses in the field
Let c = number of cows in the field
There are 2 more horses than cows in the field. Therefore
h = c + 2
or
c = h - 2 (1)
There are 15 animals in the field. Therefore
h + c = 15 (2)
Substitute (1) into (2).
h + (h - 2) = 15
2h - 2 = 15
Answer:
The correct equation is
2h - 2 = 15
Answer:
4
Step-by-step explanation:
The common ratio is found by taking the second term and dividing by the first term
12/3 = 4
We can check by taking the third term and dividing by the second
48/12 = 4
The common ratio is 4
The minimum of this graph is the focus of the parabola. I'm not sure with the maximum though but I think it doesn't have a maximum because the y value of the parabola will extend infinitely upward.
-3(2x-4)+8x-8
-6x+12+8x-8
2x+4
x=2
