why was the value of y for the function y =5x + 1 always be greater than that for the function y=4x+2 when x>1

1 answer:

6 0

Lets compare both equations so we can explain the reason for it, and see it clearly:
y1 = 5x + 1
y2 = 4x + 2
y1 > y2
5x + 1 > 4x + 2
To see why that happens we need to solve for x:
5x - 4x > 2 - 1
x > 1
Therefore, the first equation is greater than the second for values of x > 1

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
