lyle bought a baseball card for 800 dollars. if the value of the card decreases by 1.5 percent each year, find the value of the card after 12 years

667.30

Step-by-step explanation:

Well we can right this equation as 800(.985)^x  it's an exponential function then we substitute x for 12 and get 667.30

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
