The equation is y = 63/x
And y = 3 when x=21
Step-by-step explanation:
When y varies inversely with x, The inverse proportion is given by:
y ∝1/x
When the proportionality symbol is removed, a constant of proportionality is introduced

Putting y = 7 and x = 9

So,

Putting x =21

Hence,
The equation is y = 63/x
And y = 3 when x=21

Answer:
The answer is E
Step-by-step explanation:
We first are going to look at our first term on the table(the number that comes up first) which is $75.
Then we have to find the common factor. So, you divide the second number by the first number( 88.50 divided by 75 which gets us 1.18).
<em>Now, since we found the first term and the common factor, we are going to have to find the exponent for our f(x) equation. </em>
<em>We know that she bought the painting in 2009! Now the problem is asking how much the painting will cost in 2030. So, you will subtract 2030-2009 which gets you 21! So 21 is your exponent!</em>
<em>Equation: </em><em> F(x)= 75(1.18) ^21 </em>
<em>The answer that you get is: $2424.28</em>
