Answer:
x is all real numbers
Step-by-step explanation:
The domain is the input to the function. It is the values that x can take.
For this function, x can be any real value
Let Alex's age is x and June's age is y y - x = 7 .........(1)
(x+5) + (y+5) =31
x + y = 21 .........(2)
by adding 1 and 2
2y = 28
y = 14
x = 7
R = 14
s = 11
2(14)+2(11)=50
28+22=50
2(14) - 11 =17
28 - 11 =17
