The two other transformations are the width of the parabola (vertical stretch or sink) and a reflection about the x-axis if the parabola becomes negative.
First you would do 185-57 which gets you 128 next divide it by 2 which gets you 64 so Angelo has 64 and Dean has 121 stamps and together they have a total of 185

Answer:
Cost to buy and run the first car for 5 years=$24000
Cost to buy and run the second car for 5 years=$26000
I think we should buy the first car, because It is cheaper to buy and maintain
Step-by-step explanation:
first car:
Cost $18000 to buy
Cost $100 to maintain each month
5years =5 x 12=60months
Cost to maintain for 60months=100x60=$6000
First car cost to buy and run over the 5 year period=18000+6000=$24000
Second car:
It cost $22400 to buy
Cost $60 to maintain each month
5years=60months
Cost to maintain for 60months is 60 x 60=$3600
Cost to buy and run over the second car for 5years is 22400+3600=$26000
Certainly negative number is smaller than a positive number
So the order is 0.8 , -0.4
Here 0.8 is the greatest while -0.4 is least
Hope This Helps You!
