Let the value of the vehicle be described by the equation
V = a + bx
where x = number of years since purchase
a,b are constants.
When x = 0, V = $7500. Therefore
a + b*0 = 7500
a = 7500
When x = 7, V = $500. Therefore
7500 + 7b = 500
7b = 500 -7500 = -7000
b = -7000/7 = -1000
The equation is
V = 7500 - 1000x
The slope of this equation is the depreciation rate, and it is -$1000 per year.
Answer: $1000 depreciation per year.
Dear Noora7939, the pair of planets that exerts the strongest gravitational force is Saturn and Jupiter, since we know that both Jupiters are the same mass, we'll excuse that. Since the laws of gravity says that the bigger the mass the stronger the gravitational pull, Saturn has the stronger gravitational pull since Saturn is bigger than Mars.
a- 2/10 divide the fraction by 6
b-2/17 divide the fraction by 3
I think it is A but I'm not really sure
