Answer:
Step-by-step explanation:
n+1/2n=7/2
2n^2+1/2=7/2
4n^2+2=14
4n^2=12
n^2=3
n=radical3
 
        
             
        
        
        
Answer:

= (5-1)/(10-5)
= 4/5

Answer:
Step-by-step explanation:
Given that a farmer finds there is a linear relationship between the number of bean stalks, n, she plants and the yield, y, each plant produces
When we consider this graph as a straight line, the two points lying on the line would be
(30, 30) and (34, 28) taking n as horizontal and y vertical
Using two point equation we find that
the equation of the line is

Substitute the points as x =n

is the linear relationship between n and y
