Answer:30
Step-by-step explanation:
We have that an inverse variation in a function is given by:

We must find the value of the constant k.
To do this, we substitute the values of x1 = 12, y1 = 15.
We have then:

Clearing k we have:

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

For y2 = 3 we have:

Clearing x2 we have:
Answer:
Answer:
E=-6
Step-by-step explanation:
-5e+(-3)=27
Therefore,
-5e-3=27
Therefore,
-5e=27+3
Therefore,
-5e=30
Therefore,
e=30/-5
Therefore,
e=-6
