Pls answer this urgently i need it for my hw tmrw

analyze picture

com loses 1/4 of its value after every year it is purchased

v = original price times 1/4 x times(x represents)

v = 800*(3/4)^x

so, if x is five, then t is

800*(3/4)^5=

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
