Answer:

(-1, -1) is not a solution to the system

Step-by-step explanation:

Y = 3x - 4. Substitute the points for x and y

2 = 3(2) - 4

2 = 2 solution

y = 3x - 4

-4 = 3(0) - 4

-4 = -4 solution

y = 3x - 4

8 = 3(4) - 4

8 = 8 solution

y = 3x - 4

-1 = 3(-1) - 4

-1 = -7 not solution

If a hospital patient is given 50 milligrams of medicine which leaves the bloodstream at 10% per hour, how many milligrams of me

SpyIntel [72]

Alright
so equation is
$A(t)=Pe^{rt}$
P=initial amount
and t=time
r=rate

given
initial amount is 50
rate is 10%, but decreasing by 10% so -0.1
and time=6

$A(6)=50e^{-0.1*6}$
$A(6)=50e^{-0.6}$
A(6)=27.4406
about 27mg
