Answer:
k = 36 and r = 8
Step-by-step explanation:
Given that r varies directly as p and inversely as q² then the equation relating them is
r =
← k is the constant of variation
To find k use the condition r = 27 when p 3 and q = 2, thus
27 =
( multiply both sides by 4 )
108 = 3k ( divide both sides by 3 )
k = 36
r =
← equation of variation
When p = 2 and q = 3, then
r =
=
= 8
The solution of 2 equations is the point on the grid where they intersect. The 2 equations which intersect at (-1,5) are A and B
Its the first choice.

so, let's first change the bounds from 1 to 9, so we'll be dropping the indices by 1, in order to do the variable "n".
however, let's use a variable hmmm say "k", where "k" is the value of "n" beginning at 1, thus
k = n - 1.
however, if k = n - 1, then
k + 1 = n. So let's use those fellows then,
