The life of an AA battery can be predicted by the number of hours of use. As the number of hours of use increases, the remaining battery power decreases. The linear association is demonstrated in the scatter plot below. If Tyler used 20% of the battery in his AA battery, for approximately how many hours has he used the battery?
•6 hours
•24 hours
•27 hours
•40 hours

Step-by-step explanation:

I think he has used a proximetly 24 hours of the batteriey

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
