Answer:
The center is:
(2, -4)
Step-by-step explanation:
We have the following equation
The general equation of a circle has the following form
Where r is the radius and the point (h, k) is the center of the circle
To transform the given equation in the general equation of a circumference we must use the method of square completions
Step 1
<u>Step 2</u>
<u> </u>Add and subtract 
For an equation of the form
<u>Step 3 </u> Factor the expressions within the parentheses
<u>Step 4 Simplify</u>
Finally
The center is:
(2, -4)
Rise indicates going up or down on the grid
2x2x3x3, this is the prime factorization of 36
Answer:
The situation you are describing can be written as y=2x, or in this case t=2f, for every fragrance purchased there are 2 ounces of lotion that are given. Since the ounces of fragrance are not shown in this question, we can only make the graph on the ounces of lotion for every fragarance purchased. The points of the graph represent that for every fragrance bought, there is twice the amount of that in ounces of lotion. In summary, the rule is t=2f where t would equal purchases of fragrance and f would equal the ounces of lotion.
(If there is any more you would like to add to the question I can answer that.)
