Step-by-step explanation:
since y is inversely proportional to x the equation relating them is
y =
← k is the constant of proportionality
to find k use the given condition when y = 7, x = 9
k = yx = 7 × 9 = 63
y =
← is the equation connecting them
when x = 21, then
y =
= 3
157, 263, and 3163 are all prime numbers
