Answer:
2.1
Step-by-step explanation:
ANSWER
y varies inversely as x exponent 4.
EXPLANATION
The inverse variation equation is given as:

We can see that there is an inverse relation between the quantity y and x.
If the it were
, we say y varies inversely as the square of x.
Hence for the given relation,the precise definition is that, y varies inversely as x exponent 4.
Answer:
unit rate = 14x
y = 14x + 0
Step-by-step explanation:
y = mx
y = 14x

On the graph we have points x:y of
3:5
6:10
12:20
which are all in the ratio 3:5, a slope of 5/3.
3:5=9:y
y=9×5/3 = 15
Answer: C (9,15)
