Answer:
B. Distributive property
Step-by-step explanation:
The distributive property says
You are given the expression
Denote
then your expression is
Here, you can see that distributive property was used.
Now, change c into the 
again
to get the distributive property for the initial expression
I think these two are the right answer.
The location of K(1,-3) after dilated by a scale factor of 1 is K’(1,-3) also
The number of bacteria will modeled using exponential growth function, this is given by:
f(x)=a(b)^x
where
a is the initial amount
b=ratio of growth
x=time
Thus from our information we shall have:
f(x)=R(t)
a=1000
b=r
t=x
hence we shall model the situation by:
R(x)=1000(r)^t
Hence in 3 years time the population will be modeled by the function:
R(x)=1000(r)^3=1000r³
