In 2013 your car was worth $12,500. in 2015 your car was worth $8,200.
a) suppose the value of your car decreased at a constant rate of change. define a function f to determine the value of your car (in dollars) in terms of the number of years t since 2013.
b) suppose the value of your car decreased exponentially. write a function g to determine the value of your car (in dollars) in terms of the number of years t since 2013

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.
