Find the equation of the line that passes through the point (-4, 15) and is perpendicular to y = -2x-9.

Step-by-step explanation:

Alright, lets get started.

The line is perpendicular to

The slope of this equation is -2.

The slope of the line, perpendicular to this line will be :

line equation is passing through the point (-4,15) will be :

............. Answer

Hpe it will help :)

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)
