What is the solution to the following system?
4x + 2y – 2z = 1
2x + 8y + 4z = 32
30x + 12y – 4z = 24
a.(-2, 5, 1)
b.(-2, 6, -3)
c.(1,2,3)
d.(2,-4, 0)

c  is the answer or d one of them

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)

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
