The 3rd answer, when m is next to a number it means “per” for something like per second or (in this case) per minute, etc...
Let
x--------> the time in hours
y-------> the distance in miles
we know that
The speed is equal to
in this problem
<u>Equation First Train</u>
<u>Equation Second Train</u>
---------> equation 
Substitute the values of 
and 
in the equation
Solve for x
therefore
<u>the answer is</u>
Answer:
It's not. b = 15p
Step-by-step explanation:
The <em>division property of equality</em> says you can divide both sides of an equation by the same number without changing the values of the variables. When we divide both sides of the given equation by 2, we get ...
2b/2 = 30p/2
b = 15p . . . . . . . simplify
Keith's bank account starts with $250 and he adds $150 to it every month. If <em>m</em> is the number of months that have passed, then the amount of money (in dollars) in his account is given by
250 + 150<em>m</em>
<em />
Victoria's account starts with $2000 and she removes half of it each month. So after <em>m</em> months, her account has a value of
2000/2^<em>m</em>
<em />
If you were to plot these amounts, then
(a) Keith's account's value is indeed linear - TRUE
(b) Keith is constantly adding money to his account, so its value is increasing - FALSE
(c) Victoria's account's value involves an exponential expression - TRUE
(d) Victoria is removing money, so the value is decreasing - TRUE
Your answers are correct except for (c).
