Answer:
The number is 86
Step-by-step explanation:
Let the number be , then the reverse is
The sum of the reversed number and the original number is 154,
We simplify this to get:
....eqn(1)
If the ones digit in it is 2 less than the tens digit, then
....eqn(2)
Putt equation (2) in (1)
Put x=8 in the second equation:
The original number is 86
Step-by-step explanation:
Answer:
A) The indicated values of F(x) for x=-3 and x=5 are and
B) The domain of f is the set of all real numbers
Step-by-step explanation:
Given that the function F is defined by
for x=-3,5
A) To find F(x) for the indicated values of x :
Given for x=-3,5
Therefore
Therefore
The indicated values of F(x) for x=-3 and x=5 are and
B) To find the domain of f :
The domain of the f in the given expression is the set of all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
The domain of f is the set of all real numbers
