Answer:
Step-by-step explanation:
3
+x-3= - 5x
combine like terms
3 += 4
x -5x = -4x
then combine 4 and -4x
Here you go:
3 to five or 5 to 3
The population of the bacteria after 7 hours is 230 bacteria.
An exponential function is given by:
y = abˣ
where y, x are variables, a is the initial value of y and b is the multiplier.
Let y represent the population of bacteria after x hours.
Given that he starts his experiment with 200 bacteria, hence
a = 200
The bacteria grow at a rate of 2% per hour, hence:
b = 100% + 2% = 1.02
The exponential equation becomes:
y = 200(1.02)ˣ
After 7 hours:
y = 200(1.02)⁷ = 230
The population of the bacteria after 7 hours is 230 bacteria.

Since 200 is a constant, of x, move 200 out of the integral. 200x+c. Constant is a fixed value that does not change.
