Answer:
a₄ = - 15
Step-by-step explanation:
Using the recursive formula and a₁ = 17 , then
a₂ = a₁ - 8 = 17 - 8 = 9
a₃ = a₂ - 8 = 9 - 8 = 1
a₃ = a₂ - 8 = 1 - 8 = - 7
a₄ = a₃ - 8 = - 7 - 8 = - 15

Answer:the unit rate is $0.5
Step-by-step explanation:
Andre rents a bike for a day. The rental changes can be determined by the equation: R = $0.5d, where R is rental changes and d is number of days she rents the bike.
The unit rate multiplied by the number of days for which the bike was rented would give the total rental charge. From the given equation, the unit rate would be $0.5
