Since the temperature keeps increasing by 2°F each hour for the next 7 hours, the graph will be a straight line graph.
Let T be temperature
t be the time at temperature T
At t₁ = 0, T₁ = 43°F
At t₂ = 1, T₂ = 45°F (temperature increase by 2°F)
Using the straight-line formula to get the equation of the graph. The equation is expressed as T = mt + b
- m is the slope
- b is the intercept
Get the slope
Get the intercept
Substitute m = 2 and the coordinate (0, 43) into the expression
43 = 2(0) + b
43 = b
b = 43
Get the equation of the line
T = 2t + 43
Graph the equation of temperature over time

Answer:
C. 5 meters
Step-by-step explanation:
The equation that models the distance traveled (in meters) by an frog is ,where d is the distance
traveled in meters and t is the time in minutes.
To find the distance traveled in 25 minutes, we substitute t=25 into the equation and solve for d.
meters.
Therefore the frog traveled 5 meters in 25 minutes.

Step-by-step explanation:</h2>
Deflation happens naturally when the money supply of an economy is fixed. When money gain purchasing power, the producer need less capital to produce their product, which means that they can afford to sell their product with lower price. This allows one to buy more goods and services than before with the same amount of currency. So the price of money fall as there is a decrease in money supply.
