Hello from MrBillDoesMath!

Answer:

 (g o f)(0) cannot be evaluated

Discussion:

(g o f)(0) = g ( f(0))  if it exists but f(0) is not defined (as division by zero is not defined) so   (g o f)(0) cannot be evaluated

Thank you,

The sum of two numbers is at least 30 and the difference between the two numbers is less than 8. X and y are the two numbers suc
vaieri [72.5K]

Answer:

1 Expert Answer

Let x and y be the two numbers. Then by assumptions we have x+y=30 and x-y=20. Hence, y=x-20 and by plugging this into the first equation we obtain x+x-20=30 or 2x=50 or x=25 and y=5

Step-by-step explanation:

So, divide 30 by 2 . That gives you 15 for x, 15 for y. Now, you have difference of six, divide by two, that equals 3.
