We have been given a system of equations 
and 
. We are asked to find the solution of our given system of equations.
To solve our system of equations, we will equate both equations as:
Upon substituting in equation , we will get:
Therefore, the solution of our given system of equations would be 
and option A is the correct choice.
ANSWER
The value of x is
EXPLANATION
F is the point of intersection of the medians of the triangle,
The ratio is
This implies that,
We can write this as a fraction to get,
We cross multiply to get,
Let us expand the brackets yo obtain,
We group like terms to get,
We divide both sides by 2 to get,
The correct answer is B.
Answer:
c) (7, 9)
Step-by-step explanation:
Simply add the corresponding coordinates.
These ad agencies must focus on their target audience, which are the students. Hence, they should gather data on the pool that will surely comprise of students. For agency B, social media posting is not a good source pool. It's true that students are very participative and opinionated in social media. However, they can't be sure that these are students. Some parents are in social media, as well. Some are working individuals, and some are out of school youth. Unlike agency A, agency B has to sort out profiles first and identify which ones are students. Hence, agency A will produce a fair sample of the student population because it is unarguably true that everyone in the school enrollment data are students.
The answer is B.
