"Per" means "divided by", so "cost per ounce" means "cost"/"ounces".
The difference in cost per ounce is
.. (1.14/12) -(1.28/16) = .095 -.08 = 0.015
Brand X costs 1.5¢ more per ounce than Brand Y.
If you mistyped the question and you meant y=1/4x to the power of 0.5X then yes it's a function, but if you didint mistyped it then no because it cannot be graphed
Answer:
Solving the expression
we get 
Option D is correct option.
Step-by-step explanation:
We need to solve the expression: ![\frac{\sqrt[3]{7} }{\sqrt[5]{7} }](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5B3%5D%7B7%7D%20%7D%7B%5Csqrt%5B5%5D%7B7%7D%20%7D)
We know that
and ![\sqrt[5]{x}=x^{\frac{1}{5}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7Bx%7D%3Dx%5E%7B%5Cfrac%7B1%7D%7B5%7D)
<u>Using above rule:</u>
<u />
<u />
Now, we know the exponent rule if bases are same and divided then exponents are subtracted i.e:
<u />
Using the exponent rule

So, solving the expression
we get 
Option D is correct option.
Answer: -0.5
Step-by-step explanation:
We can see that at x=0 that Y=2, when x=2, y=1, so we do the x1 - x2 = -2 and y1-y2 = 1
Then we do 1 / -2 = -0.5
The average rate of change is -0.5
