d
Step-by-step explanation:
Where is table y?
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.
The function of the trapezoid area is:
A(x)=(B+b)*h/2
Where B and b are the bases and h is the height.
With the given data: h=10 B and b =7 and x (it may vary which one is bigger)
-----------
So that function becomes:
A(x)=(7+x)*10/2
A(x)=(7+x)*5
----------
So if you want the inverse function, you have to operate to find x:
A(x)/5=7+x
A(x)/5-7=x
----------
So the new function is:
x(A)=A/5-7
