A random sample of dogs at different animal shelters in a city shows that 15 of the 55 dogs are puppies. The city's animal shelters collectively house 1,540 dogs each year. About how many dogs in all of the city's animal shelters are puppies?

middle maybe?

step-by-step explanation:

2*3^2

step-by-step explanation:

d. 5

step-by-step explanation:

f(x) + n - shift a graph n units up

f(x) - n - shift a graph n units down

f(x + n) - shift a graph n units to the left

f(x - n) - shift a graph n units to the right

on the picture we can see:

the graph g(x) was made by shifting the graph f(x), 5 units to the left.

therefore g(x) = f(x + 5) → k = 5

look at the picture.
