Answer:
(0,2) is one solution of the solution set of the equation x + 3y = 6.
(0,2) is not an element of the solution set of the equation -x + y = 8.
Step-by-step explanation:
We have the system of equations, x + 3y = 6 and - x + y = 8.
Now, we have to check whether the solution set for that system of equations or not includes the point (0,2) or not.
Here, the equation x + 3y = 6 is satisfied by the point (0,2).
Hence, (0,2) is one solution of the solution set of the equation x + 3y = 6.
But the equation - x + y = 8 is not satisfied by the point (0,2).
So, (0,2) is not an element of the solution set of the equation -x + y = 8.

D is the correct option
Step-by-step explanation:
The roulette can land in any possibly slot and their are 38slots
i.e the total possible event is 38
Green slot = 2
Red slot =18
Black slot =18
P(G)=2/38 =1/19
P(R)=18/38=9/19
P(B)=18/38=9/19.
The roulette will be spun twice and they are independent i.e. the occurrence of one event does not affect the occurrence of the other.
We are looking for the probability of red first and probability of black
P(R n B)=P(R)P(B), since they are independent
P(R n B)=9/19×9/19
P(R n B)= 0.2244
D is the correct option
Answer:
117
Step-by-step explanation:
117^2 = 13689
Simplify the following:
sqrt(13689)
sqrt(13689) = sqrt(81×169) = sqrt(3^4×13^2):
sqrt(3^4 13^2)
sqrt(3^4 13^2) = sqrt(3^4) sqrt(13^2) = 3^(4/2)×13^(2/2) = 9×13:
9×13
9×13 = 117:
Answer: 117
