Answer:
8 cookies: 1 cookie =$1.25
12 cookies: 1 cookie =$1.33
Step-by-step explanation:
The formula for price per unit is : 
Lets first work out the price per unit for the 8 cookies. You can do this by dividing the price of 10 by the amount of 8, this gives you $1.25. This means that the price per cookie is $1.25.
Now to work out the price per cookie for 12 cookies. You can do this by dividing the price of 16 by the amount of 12, this gives you $1.33. This means that the price per cookie for this offer is $1.33.
1) Divide 10 by 8.

2) Divide 16 by 12.

Answer:
The leftmost graph [with the points (-3,-3) and (0,3)]
Step-by-step explanation:
y+3=2(x+3)
y+3=2x+6
y=2x+3
The y-intercept is 3, meaning that the line passes through the point (0,3), and it's slope is 2, so it travels 2 units up and 1 unit over. Thus the correct graph is the top left graph, with the two points (-3,-3) and (0,3).
Hope this helps! (:
Step-by-step explanation:
replaced f(x) with 5
5= x^2 +4
5 -4 = x^2
1 = x^2
take the square root on both sides
- 1 or 1 = x
