Answer:
It is a function.
Step-by-step explanation:
Functions are relations in which one domain value is assigned to exactly one range value. The x-value must not repeat in the relation set for it to be a function.
{(2,3), (4,3), (6,3), (5,9), (3,9)}
There are no repeating x-values given.
The relation should be a function.
Hope this helps.
Answer:
Age of younger brother is 14 years..
And age if elder brother is 29 years.
Step-by-step explanation:
Let us denote 'x' as the age of smaller brother,
then, the age of younger brother will be x+15 years.
Equation formed:-
x+x+15 =43
2x+15 = 43
2x = 43-15
2x = 28
X = 28/2
X = 14
Age of younger brother is 14 years.
Age of elder brother = x + 15
Age of elder brother 14 + 15 = 29 years.
