see explanation
Step-by-step explanation:
Given x and y are in proportion then the equation relating them is
y = kx ← k is the constant of proportion
To find k use an ordered pair from the table
Using (2, 10 ), then
10 = 2k ( divide both sides by 2 )
5 = k , thus
y = 5x ← relationship between x and y
Ответ:
3^2 = 9
8 * 9 * 5 = 360
15 is a factor of 360, so the answer would be 1. Fifteen is a factor of the number because both 3 and 5 are prime factors
