What is the equation of the following line (4 -3) (0 0)
a. y= -3x
b. y= 1/4x
c. y= 3x
d. y= -3/4x
e. y= -4x
f. y= -4/3x

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)

i don't see any
