Question

Let A={1,2,3,4,5} and B={4,6,9} be two sets. Define a relation R from A to B byR={(x,y):x-y is a positive integer}, find (x+1,y-2)=(3,1), and hence write R in the

Roster form. ​

Answer 1

Step-by-step explanation:

A={1,2,3,5} and B={4,6,9}

R={(x,y): the difference between x and y is odd x∈A,y∈B}

∴R={(1,4),(1,6),(2,9),(3,4),(3,6),(5,4),(5,6)}

Answer 2

Answer:

x=2 y= 3

Step-by-step explanation:

b)

(x+1,y-2)=(3,1)

=> x+1 = 3 ie x = 3-1 =2

=> y-2 =2 ie y = 1+2 = 3

a)

A X B =

{(1,4) (1,6)(1,9)(2,4)(2,6).(2,9) (3,4).(3,6)(3,9)(4,4),(4,6)(4,9)(5,4).(5,6).(5,9)}

then R = {(4,4),(5,4)}

4-4 =0

5-4 =1

positive integer
