The profit a hot dog vendor earned, in dollars, is proportional to the number of hot dogs sold. This equation represents the proportional relationship between

the profit earned (p) and number of hot dogs (h) sold.

p = 2h

Enter the profit, in dollars, earned for each hot dog sold.

The profit, earned for each hot dog sold is $2

Step-by-step explanation:

Let

p> the profit earned

h---> the hot dogs sold

we know that

p= 2h

so

The slope or constant of proportionality is equal to

 m=2 $/hotdog

therefore

For  h=1 hotdog

The profit is  

p=2(1)=$2

$2

Step-by-step explanation:

You have 1 hot dog (h), and you MULTIPLY IT by 2 (2h) to get the profit. So you have 1 times 2, which is 2.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
