Answer:

1. 4x - y is less than or equal to 4 and 2x - 2y is less than or equal to 3

Step-by-step explanation:

Blue line:

y > 4x - 4

y - 4x > -4

4x - y < 4

Test point: (0,0)

4(0) - 0 = 0 < 4

Red line:

y > x - 1.5

2y > 2x - 3

2x - 2y < 3

Test point: (0,0)

2(0) - 2(0) = 0 < 3

While testing a new vaccine, a lab technician noticed that the number of bacteria reduced by half every minute. How long does it

son4ous [18]

To start, find your equation, n=3000(.5)^t, n being your number of bacteria and t being your time. Now plug in 375 for n and solve for t, 375=3000(.5)^t, .125=.5^t, $t=log_{.5} .125=3$ . This means your answer is 3 minutes. To check it, plug it into your equation. n=3000(.5)^t=3000(.125)=375
