A
B
C
D

1) False

2) Option 2

Step-by-step explanation:

1) Given equation is

=>

y in terms of x :

=> 4y = 12 - x

=> y =

So, it is false, since y is not equal to 12-x

2) y = (Done in (1))

=> y =

=> y =   (Option 2)

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
