1. the table shows values of a function . what is the average rate of change of over the interval from x = 5 to x = 9? show your work.

x 4 5 6 7 8 9 10

8 10 11 14 18

Average change of rate = 4

Step-by-step explanation:

The average rate of change is going to be the final value mines the initial value, divided by the change in the input of the function.

Average change of rate = (14 - (-2)) / 9 - 5 = 16/4 = 4

45 minutes

step-by-step explanation:

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
