The following equations when graphed will contain the sides of a polygon. Without graphing the lines, make a prediction about what kind of figure the lines will create. Support your prediction with information you know from the given equations. y = 1/2x + 3 y = 1/2x – 2 y = 2x + 1 y = 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)

it should be a.

hope it
