Using permutation formula;

This implies that





Answer:
128 ÷ 16 = 8
so 8 dog food for every dog
First, simplify the (x+2)(x+2) with FOIL:
f(x)=(

)-3
Combine like terms
f(x)=

Then you have standard form.
Hope that helps.
The slope of x-y=8 is 1 because it's actually y = x-8
Parallel means the slope is equal to 1 as well.
