Answer:
Step-by-step explanation:
1 for both
For this case we have the following functions:

We must find the following sum of functions:
(f + g) (x)
By definition we have to:

So, we have to:

Answer:

5x-6><span>9
--------------------
Add 6 on each side of the equation
</span><span><span>5x-6</span>+6</span>><span>9+6
</span><span>5x</span>><span>15
</span>--------------------------
Divide each side by 5
5x ÷ 5 > 15 ÷ 5
x > 3
-------------------------------------
x > 3 is your answer
Answer:it a
Step-by-step explanation:
Answer:
P (She selects the route of four specific capitals) = 
D. No,it is not practical to list all of the different possible routes because the number of possible permutations is very large.
Step-by-step explanation:
Let's start assuming that each route is equally likely to be chosen.
Assuming this, we can calculate P(A) where the event A is ''She selects the route of four specific capitals'' doing the following :
P(A) = Favourable cases in which the route of four specific capitals is selected / Total number of ways in 4 of 42 states
The favourable cases in which the route of four specific capitals is selected is equal to 1 .
For the denominator we need the permutation number of 4 in 42.
The permutation number is defined as :


The probability of event A is : 
Finally for the other question : The option D is the correct because the number of possible permutations is 2686320 and is very large to be listed.
