Answer:

Step-by-step explanation:
Given:
Two points are given
x = number of minutes
y = length of the lin
⇒ (0, 6)
⇒ (20, 17)
We need to find the equation that represents the relationship between x, y.
Solution:
Using slope formula to find the slope of the equation of the line.

Substitute
= (0, 6) and
= (20, 17) in above equation.

So, slope of the line 
Using point slope formula.
------------(1)
Where, m = slope of the line
Substitute
⇒ (0, 6) and
in equation 1.


Add 6 both side of the equation.


Therefore, the equation that represents the relationship between x and y is written as:

The value of y should be 8
Answer:
c(n) = 4n +20
let m = c(n)
m= 4n +20
make n the subject
<u>m</u><u> </u><u>-</u><u>2</u><u>0</u><u> </u><u> </u> =n
4.
inverse function of c(n)= <u>n-20</u><u> </u>
4
It is a must that one replaces the m with the n in order to get the final answer
Answer:
none of them are true
