Answer:A:28.8
Step-by-step explanation:
For this case we have that an inverse variation in a function is given by:

For this case, we must find the value of the constant k.
To do this, we substitute the values of x = -4, y = 8.
We have then:

Clearing k we have:

Substituting the value of k we have that the inverse variation is:

Answer:
Lauren's percent error = 13.95% Approx
Step-by-step explanation:
Given:
Number of photos predict = 129
Number of photos actual = 111
Find:
Lauren's percent error
Computation:
Lauren's percent error = [(Number of photos predict - Number of photos actual)/(Number of photos predict)]100
Lauren's percent error = [(129 - 111)/129]100
Lauren's percent error = [(129 - 111)/129]100
Lauren's percent error = [(18)/129]100
Lauren's percent error = 13.95% Approx
