Question

4. Express {(x, y): y + 2x = 5,x,y belongs to W} as the set of ordered pairs.​

Answer 1

Answer:

v b

Step-by-step explanation:

Answer 2

Answer:

A={(0,5),(1,3),(2,1)}

Step-by-step explanation:

Here, W denotes the set of whole numbers

We have 2a+b=5 where a,b∈W

∴a=0⇒b=5

⇒a=1

⇒b=5−2=3

and

a=2

⇒b=1

For a>3, the values of b given by the above relation are not whole numbers.

∴A={(0,5),(1,3),(2,1)}
