Considering that Livia eats chicken drumsticks with 11 grams of protein and cheese sticks with 7g of protein, we can determine that for each chicken drumstick, she will receive 11 grams of protein.
For each cheese stick, she will eat 7g of protein.
If she eats 10 cheese sticks, she will eat 70 gram of protein.
This funciton is dependent on the amount of cheesesticks she's eaten.
Answer:
a) The center coordinates O is (0,0)
b) The radius C = 15
Step-by-step explanation:
The given equation of the circle is : 
Now, general form of the equation of the circle is:

where (h,k) are the center co -ordinates and r is the radius of the circle.
Comparing the general equation with the given equation, we get

So, here the center coordinates (h,k) = (0,0)
And the radius of the given circle is r = 15
The answer to this question is 4x= y-4
C is 0, since only multiplied by 0 will get 0, and the question defined that a and b not 0, so only c is 0
