Answer:
a=3
Step-by-step explanation:
x – 2y = 4
ax– 6y = 12
To have infinitely many solutions, the two equations have to be equal
Multiply the first equation by 3
3x -6y = 12
ax -6y = 12
a = 3
Option A: All real numbers is the right answer
Step-by-step explanation:
First of all, let us define domain
Domain is the set of all inputs to a function on which the function is defined
So
Given function is:

The given function will not be undefined for any value of x as there is no denominator which will make the function approach infinity
Hence,
Option A: All real numbers is the right answer
