Y varies inversely with x. When x = 3 then y = 5. Write a function to represent this relationship.
Mariulka [41]

Answer:

<em>The function to represent this relationship will be:  y= \frac{15}{x}</em>

Step-by-step explanation:

y  varies inversely with  x. That means......

y= \frac{k}{x}..............................(1)  

where k is a proportional constant.

Given that, when x=3, then y=5

Plugging these values into the above equation, we will get.....

5=\frac{k}{3}\\ \\ 5(3)=\frac{k}{3}(3)\\ \\ 15=k

Now plugging this k=15 into equation (1).....

y= \frac{15}{x}

So, the function to represent this relationship will be:  y= \frac{15}{x}

Answer:  - \frac{9}{z^5}

Explanation:

The simplification of that expression is done in this way:

1) The negative sign is placed in front of the whole fraction

2) 27 is divided by 3 resulting in 9: 27 / 3 = 9

3) x^2 on the numerator cancels out with x^2 of the denominator

4) z on the numerator is cancelled out with 1 z of the denominator and the result is z^5 in the denominatoir.

All that yields to :
    
      9
- --------
    z^5

Using the math editor it is:  - \frac{9}{z^5}
