The distance of the hiker of a linear function.
The true statement is <em>(d) The y-intercept is (0, 2), and the 2 represents the number of miles from the car at the start of this time period.</em>
From the graph, we can see that the graph crosses the y-axis at: (0,2)
This means that, the y-intercept is (0,2), and 2 represents the number of miles, he started with.
Hence, the correct statement is (d)

Answer:
First you need to set up an equation y = mx + b. m would be the monthly charge and b would be the one time fee. x represents the number of months.
To solve for the number of months with a total price of 240 we substitute 240 in for y and solve for x.
240 = 25x + 40
subtract 40 from each side
200= 25x
divide by 25
8 = x
8 months
10 + 7r = 45
7r = 35
r = 5

Answer:
Step-by-step explanation:
The rate of change in the temperature T of coffee at time t is written as 
(remember derivatives are used to express rates of change, and in our case the rate of change of the temperature T). The difference between the temperature M of the air at time t, and the temperature T of the coffee at time t can be expressed as 
Saying that the rate of change in the temperature T is proportional to the difference between M and T is just a way of saying that the rate of change in the temperature T is equal to the difference between M and T, multiplied by some constant k (whose value we don't know, but still that's what it means).
Therefore we get
The numerator of the fraction is the power of the number and the denominator is the root of the number. This is expressed as follows:
⁴√(3)³
