What is the equation of this graphed line? a graph with a line running through coordinates (0, 7) and coordinates (8, -2) enter your answer in slope-intercept form in the box.

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)

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.
