Answer:
the missing exponent is 3
Step-by-step explanation:
You will have to complete the square
factor the 4 out of the first two terms
y = 4(x^2 - 2x) + 5
x^2 - 2x + 1 = (x - 1)^2
we want what we have to look like this
the difference between (x^2 - 2x) and (x^2 - 2x + 1) is the +1
so we add a 1 and subtract a 1 to keep balance
y = 4(x^2 - 2x + 1 -1) + 5
y = 4(x^2 - 2x + 1) - 4 + 5 [moved the extra -1 out of it and distributive property]
y = 4(x - 1)^2 + 1 [factored and added like terms]
y = 4(x-1)^2 + 1
or
y - 1 = 4(x-1)^2
is now in vertex form.
Answer:
The answer would be 20. Since the store sells 1/5th of a box each day, it takes 5 days to sell one box. There are four boxes, so multiply 5 by 4 and you get 20.
