<span>9, 12, 19, 30, ...
</span>formula for the nth term is;
<span>2n^2 + 3n - 10</span>
You have to multiply 15 by 32 and you get 480 which means the publisher shipped 480 books to the bookstore
It would be subtraction I think
Inverse variation equations take the following form:
y = a/x, where a is some constant
We know x=3, y=16 and x=6, y=8 satisfy the equation.
Let's find the value of a.
16=a/3
Multiply both sides by 3
16*3 = a
48 = a
Thus, the equation is:
y = 48/x
You can use the other values of x and y to test, but I'm sure this is the correct equation. :)
