Y=-1/4x+7.5 is the right equation
The domain is -1, 0, 1, 2, 3, 4. Hope this helps.
An estimate for the number of ducks would be 62.
There were 30 the first day.
The second day, 8 of those 30 were there as well, so we subtract that from the 40 ducks and get 32.
Add 30 and 32 to get our estimate.
Answer:
Step-by-step explanation:
Given f(x)=
We have to find
In order to find we have to make x as the subject of the formula
Let us assume f(x)=y
⇒
Subtracting both sides by 5
Dividing both sides by 2
⇒
Now substituting y with x
we have
Now
=
So option (ii) is correct
