Which line is not perpendicular to the line y=1/3x-2 A. y=-3x
B. -6y=-2x+12
C. 4y=-12x+8
D. y-1=-3(x+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)

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.
