Answer:
Step-by-step explanation:
x (3,7,11,15)
y (4,6,8,10)
A. This IS a function because u have no repeating x values
B. Data in table : 
     when x = 11, y = 8
    relation : f(x) = 5x - 21....when x = 11
                   f(11) = 5(11) - 21
                   f(11) = 55 - 21
                   f(11) = 34.....so when x = 11, y = 34
therefore, the relation f(x) = 5x - 21 has a greater value then the table
C. f(x) = 5x - 21......f(x) = 99 
    99 = 5x - 21
    99 + 21 = 5x
    120 = 5x
    120/5 = x
    24 = x <====

Answer:
first get a common denominator  by multiplying 7 and 4 to get  28
28 is our common denominator here.
Step-by-step explanation:
We want to add the fractions   2/7 and 1/4
(2/7) * (4/4)   and    (1/4) * (7/7)
(2/7) * (4/4)   +   (1/4) * (7/7) =  8/28  + 7/28 = 15/28
 
        
             
        
        
        
28 because we are talking about TENS meaning there can only be 2 digits
