10 years.
at first i thought u was messing around because who would want to buy a magic carpet.
Answer:
47y-4z-4-30x
Step-by-step explanation:
9
Think of it like you are going up so -11+20=9
X² + 10x + 29 = 0
x = -(10) ± √((10)² - 4(1)(29))
2(1)
x = -10 ± √(100 - 116)
2
x = -10 ± √(-16)
2
x = -10 ± 4i
2
x = -5 ± 2i
x = -5 + 2i or x = -5 - 2i
THe roots of the function is 5 ± 2i.
Assuming that this is a linear relationship you must find the rate of change...$23.81-$20.70= $3.11. 3.11 is how much it changed that year. What that also gives you is how much you bought the post for at 0 years by subtracting $20.70 and the $3.11 = the price of the poster. This gives us the equation y=3.11(x)+17.59
Where Y is the value and X is the amount of years.
