 \bold{\text{Slope (m)}=\dfrac{1}{4}}Slope (m)=41

Step-by-step explanation:

A linear equation is of the form: y = mx + b   where

m is the slope

b is the y-intercept (where it crosses the y-axis)

x + 4y = 16

     4y = -x + 16

       y = -\dfrac{1}{4}x+\dfrac{16}{4}y=−41x+416

       y=-\dfrac{1}{4}x+4y=−41x+4

The y-intercept (b) = 4

Next, find the slope given point (4, 5) and b = 4

\begin{gathered}y=mx+b5=m(4)+41=4mdfrac{1}{4}=mlarge\boxed{Slope (m)=\dfrac{1}{4}}\end{gathered}y=mx+b5=m(4)+41=4m41=mSlope(m)=41

idk

step-by-step explanation:

use that smart brain

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)
