Answer: 15
Step-by-step explanation:
Let's define the concept of inverse functions.
If we have a function h(x), such that it has an inverse, and:
h(x) = y.
Then the inverse function j(x) must meet the following:
j(y) = x.
Now, we want to calculate:
h( j(15) ).
Let's suppose that:
j(15) = A.
(Where A can be any real number).
then, by the above relation, we must have that:
h(A) = 15.
Now we can replace j(15) by A in h(j(15)):
h( j(15) ) = h( A ) = 15.
Answer:
One of the number is 4 while the other is 7
Step-by-step explanation:
The sum of two numbers is eleven
Let the numbers be x and y
X+ y = 11
One number is thirty-eight less than six times the other
X= 6y-38
X+ y = 11
6y-38 +y= 11
6y+y= 11+38
7y=49
Y= 49/7
Y= 7
X+ y = 11
X+7= 11
X= 11-7
X= 4
