y = -3x + 6

Step-by-step explanation:

We can first find the y intercept by looking at y when x = 0

y intercept = 6

We can then find the slope by looking at the patterns on the tables.

As we can see, the top row's pattern is +4 every time

The bottom row's pattern is -12

Slope = rise/run

-12/4 = -3

Therefore, the equation for the chart is y = -3x + 6

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)
