What is the excluded value of x for the expression (x-4)^2/(x-9)^2
2 answers:
Answer: The excluded value of x = 9
Step-by-step explanation:
Since the Excluded values are the values that will make the denominator of a fraction equal to 0.
Because when the denominator of a rational function equals to zero it makes it infinite.
This is why we always exclude the value from the function.
Here The given expression,
Thus, for excluded value,
⇒ x - 9 = 0 ( by taking the square root on both sides)
⇒ x = 9 ( by adding 9 on both sides )
Thus, 9 is the excluded value for the given function.

Answer:
1st statement is true.
2nd statement is false.
3rd statement is true.
Step-by-step explanation:
We have been given two inequalities and we are asked to find out whether the given statements are true or false.
represents balance of account A and
represents balance of account B.
1. We can see from our inequalities that Jeremiah initially invested $100 in account A and $50 in account B. Therefore, 1st statement is true.
2. The rate at which balance of account A grows is 1.2 and rate for account B is 1.23. Therefore, 2nd statement is false.
3. We can find total amount Jeremiah invested in two accounts by adding initial investment of both accounts, that is 100+50=150 . Therefore, 3rd statement is true.
