Yes... You have $10
your brother is supposed to give you $10
he gives you the money the friend told him to and you would have $20 PLUS the ten that he owes you. That would make you have $30. He took youre ten and gave you 20 but you were supposed to have 20 in the first place. He needs to give you the ten back he owes you.
F(x) = 7/x
g(x)=x²+10
Then f(g(x))= 7/(x²+10)
By the way g(f(x))=(7/x)² + 10
What does it take for a product of unknown factors to be null?
Answer:
60000/4 pr 15000
Step-by-step explanation:
Rate of change = change in population / change in time
80000 - 20000 = 60000
January to April is 4 months
so the rate of change will be 60000/4 or 15000
