• Rob bought a house for £145 000 The value of the house depreciated by 4% in the first year.
The value of the house depreciated by 2.5% in the second year.
Rob says: "4 + 2.5 = 6.5 so in two years the value of my house depreciated by
6.5%"
Is Rob right? You must give a reason for your answer.

Acable company claims that the average household pays $78 a month for a basic cable plan, but it could differ by as much as $20. write an absolute value inequality to determine the range of basic cable plan costs with this cable company. a. |x − 78| ≥ 20 b. |x − 20| ≥ 78 c. |x − 20| ≤ 78 d. |x − 78| ≤ 20
