Answer:

Step-by-step explanation:
For Q1 and Q2


For Q3 and Q4

The option C) y = 15/x
a) y = 15 x is an example of direct variation, with proportionality constant = 15
b) is an example of linear variation (it is the equation of a straight line that does not pass through the origin)
c) y = 15/x => y*x = 15 = constant which is the characteristic of an inverse relation
d) y = x/15 is an example of an inverse relation, with proportion constant = 1/15
Answer:
n = 5
Step-by-step explanation:
Coordinate of P = (n,3)
R is on y-axis & the y-coordinate of P & R are equal. So coordinate of R = (3,0)
Coordinate of Q = (n,-2)
Using distance formula,
Distance between P & Q =


Distance between P & R =


But in question it is given that distance between P & Q is equal to the distance between P & R. So,
