Answer:
Step-by-step explanation:
add all of them up,  Julie,   6 + 12 + 3 + 4 = 25   
there are 25 total students.  now divide each of the number of people that speak that language by the total students
6/25 = .24 = 24%
12/25= .45 = 48%
3/25 = .12 = 12%
4/25 = .16 = 16%
Also, if you want to just check,  see if the percentages add to 100%
 
 
        
             
        
        
        
It is a right angle,90° is a right angle also, triangle.
        
             
        
        
        
We are given the functions:
f(x) = 4 x – 5                       --->
1
g(x) = 3 x + 7                       --->
2
 
To find for the value of f(x) + g(x), all we have to do is
to add equations 1 and 2:
f(x) + g(x) = 4 x – 5 + 3 x + 7
f(x) + g(x) = 7 x + 2 = y
 
In this case, for any real number value assign to x, we get
a real number value of y. This is because the function is linear.
Therefore the domain of the function is all real numbers.
