108=3(b-s)
36=b-s
s=b-36
...
108=2(b+s), and using s found above gives us:
54=b+b-36
54=2b-36
2b=90
b=45, and since s=b-36, s=9
So the boat's speed is 45mph and the stream's speed is 9mph
Answer:
Step-by-step explanation:
For the first few exponents multiply and the rest they add because like terms.
The trick is that when you raise a power to a power you multiply. Otherwise you add if the base value is the same.
The linear function that models the relationship is P = 28,200 + 1950t.
<h3>What is the
linear function that models the relationship?</h3>
A linear function is a function that has a single variable raised to the power of 1. An example is x + 2
The first step is to determine the rate of increase in the population:
Rate of increase = (population in 2012 - population in 2008) / number of years
(36.000 - 28,200) / 4 = 1950
P = 28,200 + 1950t
