Write the equation of a line that passes through the point (5, 4) and is parallel to the line whose equation is 2x + y = 3

y = -2x - 6

Step-by-step explanation:

2x + y = 3

y = -2x + 3

(I personally graphed it out and found the y intercept by starting at 5,4 and using the -2x to work back to the y int.)

the correct answer is 828.07

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)
