Answer: 3/5

Step-by-step explanation:

First, you need to find the inverse of f(x)=2x+5 .

f-1(x)= \frac{x}{2} -\frac{5}{2}

Then, you'd plug in 8 into that equation, which I got \frac{3}{5\\}

Hope this helps :)

A culture of bacteria that initially contained 2000 bacteria has a count of 18000 after 2 hrs. Determine the function that expre
melomori [17]

Answer:

y= 8000x + 2000

Step-by-step explanation:

to find the formula we can use the points given in the question:

the slope:

to get the slope we can take the 2 points, (0,2000) and (2,18000) where x values are time and y values are bacteria

now using slope-intercept form we can get \frac{18000-2000}{2-0} which gives a slope of 8000 meaning for each hour there are 8000 new bacteria

intercept:

since we start with 2000 bacteria we know this is the y intercept so when x is 0

formula:

y=8000x + 2000
