When a window is open, the temperature in a room falls 5ºF every 15 minutes. Before the window is opened, the temperature was 70ºF . Use the Ray tool to make a graph that shows the temperature of the room, T, after the window has been open for m minutes.

The temp fall one degree every 3 min.

(15,65) (30,60)(45,55)

Step-by-step explanation:

I hope you know how to graph that =D

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

one fourth of 9% = 2.25%

gavin is correct in saying : the equivalent quarterly interest rate would be

2.25%.
