Xy=k, whenever the product of two variables is a constant it is called inverse variation.  This is an inverse relationship, intuitively because, as the value of one variable increases, the other decreases and vice versa.

It is easy to spot as xy=k or y=k/x.

The function d(x) = |x 100| can be used to find the number of degrees a container of water at a temperature of x degrees Celsius
Volgvan

Answer:

f(d(x)) = \frac{9}{5}|x^{100}| + 32

Step-by-step explanation:

The function d(x) takes a value of x in degrees centigrade and provides the number of degrees that a container of water at that temperature x is far from the boiling point of water.

The function f(d) takes a value d in degrees centigrade and returns a value d(x) in degrees fahrenheit.

Therefore, by doing f(d(x)) we are introducing the function d(x) within the function f(d).

So the range of d(x) now is the domain of f(d(x))

This means that the function f(d(x)) shows the <em>number of degrees Fahrenheit</em> that a water container at a<em> temperature x in degrees Celsius</em> is far from the boiling point of water.

f(d(x)) = \frac{9}{5}|x^{100}| + 32

So to add fractions they need to have a common denominator, which in this case is 24. then multiply 1 by 4 and 5 by 3 because whatever you multiply the denominator by you need to do the same to the numerator, which will get you 4/24+15/24 then you add across the numerators and you get 19/24

For part B
the fixed cost is 500 dollars because it is a set inital amount, the varibale cost is .15 because it is the cost dependent on something else (per indicated variable part)

y=.15x+500
.15 cents per flyer, add 500 because that is the set amount it costs to even create the flyer

Plug in 500 for the equation
y=.15(500)+500
y=75+500
y=575


for part a b=ka for direct variations so the direct one is C - two items directly multiplied y=mx+b for partial variation so its A,D - basically the equation of a line A is neither - shows neither of these relationships
