Which equation describes a line that passes through (6 - 8) and is perpendicular to the line described by 4x - 2y = 6?
A. y= -1/2x-5
B. y=2x-3
C. y = 2x - 20
D. y= -1/2x-3

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)

if you need just tell me and i will come to the rescue.
