Answer: 23m - 11n
Step-by-step explanation:
First, we combine all like terms
the like terms for m are: 7m, 14m, and 2m
7m + 14m + 2m = 23m
the like terms for n are: -6n and -5n
-6n + (-5n) = -11n
Then, we put them back.
23m - 11n is the final answer
Answer: Hello there!
A model to see the growth of a certain population is the exponential model.
If the initial population is P, then the model can be written as
Where t is the time, and r is growth rate.
and f(0) = P
Then we want to know the time needed for the initial population to be doubled, this is f(x) = 2P, where x is the time that we want to find.
then
then x= ln(2)/r
Answer:
Let x represents the number.
Given the statement: "Three less than the product of a number and two, increased by five".
"Product" means multiply
"Product of a number and two" translated to
"Three less than the product of a number and two" translated to 2x - 3
Increased by 5 means +5
then;
the given statement becomes;
Therefore, the expression that represents "three less than the product of a number and two, increased by five" is
Answer:
L(w) = 8 mm + (2 mm/wk)(wk)
Step-by-step explanation:
L(w) = length of beard as a function of time in weeks
L(w) = 8 mm + (2 mm/wk)(wk)
