Yes I can, MissSmartiez at your service ;)!
This calls for the distributive property. Distributive property, essentially, takes the outside value (in this case 4) and multiply it to the inside value(s) (in this case 2x and [+]3) Thus, it's basically 4 * 2x + 4 *3.
4 multiplied by 2x is 8x.
4 times 3 is equivalent to 12.
Therefore the solution is 8x + 12.
The tripling time of population is 6 days and the population will be doubled in 3.5 days.
Given that the population of a bacteria is tripling in 6 days.
We have to find the tripling time of population and the time when the population will be doubled.
Suppose the population of bacteria in beginning be x.
The population of bacteria seems like arithmetic progression in which a =x, nth term =3x and n=6.
Aritmetic progression is a sequence which is having common difference.
nth term=a+(n-1)d
3x=x+(6-1)*d
3x-x=5d
2x=5d
d=2x/5
d=0.4x
So now we have to find the value of n where population will be 2x.
nth term=a+(n-1)d
put nth term=2x, a=x,d=0.4x
2x=x+(n-1)*0.4x
2x-x=(n-1)*0.4x
x/0.4x=n-1
2.5=n-1
n=2.5+1
n=3.5
Hence the population of bacteria willbe doubled after 3.5 days.

Answer:
Step-by-step explanation:
our function is
f(x)=-0.7x
we are asked to determine the inverse of the above function . In order to do so we put f(x) = y and separate x in terms of y and in the final answer , we replace x with y and x with f'(x)
let us see how do we do that
y=-0.7x
dividing both sides by -0.7 we get
we replace x with y and x with f'(x)
