As the variation is direct we have:

We must find the value of k.
For this, we use the following data:
y = 200 when x = 5
Substituting values we have:

Clearing k:

Then, the function is:

We evaluate the function for x = -3
Answer:
the value of y when x = -3 is:
c.
72
The answer is C. 1,000,000
When the 10 is to a negative power you move the decimal to the left. in this case its 5 spots. i believe your answer is .00005003
Step-by-step explanation:
if f (x) = 100 - x;
as x increases, the value of f(x) will decrease
