M + 20 = 9
u need to subtract 20 from both sides because u want to isolate m
m + 20 = 9
m + 20 - 20 = 9 - 20
m = - 11
Answer:
Yes, but it is not linear. It is exponential :
Step-by-step explanation:
On the first day we have 5 bacteria.
On the second day we will have 5*2 = 10 bacteria.
On the third day we will have 10*2 = 5*2*2 = 5*2^2 = 20 bacteria.
On the fourth day we will have 20*2 = 5*2*2*2 = 5*2^3 = 40 bacteria.
We can see that
,
where x is a number of days and f(x) gives us the number of bacteria.

Step-by-step explanation:
The exponential function is
- a decay function, if
- an increase function, if
Thus, for the exponential function to be the exponential decay function the following must hold
17 is a prime number whereas 26,44 and 65 are the composite numbers.
<u>Step-by-step explanation:</u>
The number 17 does not belong with 26, 44 and 65.
Here 26 is divisible by 2 and 13.
44 is divisible by 2, 4 and 11.
65 is divisible by 5 and 13
But 17 is divisible by 1 and itself, that is it's a prime number, whereas the other numbers 26, 44 and 65 is divided by 1, itself and also by other numbers.
So 17 is a prime number whereas the 65, 26 and 44 are composite numbers.
