When a window is open, the temperature in a room falls 5°f every 15 minutes. before the window is opened, the temperature was 70°f . pls me! will mark brainliest

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.

See attached graph

Step-by-step explanation:

Let m be the number of minutes passed and T be the temperature (in F°)

Before the window is opened, the temperature was 70°F, then at m = 0 minutes, T = 70°F

When a window is open, the temperature in a room falls 5°F every 15 minutes. This means

at m = 15, T = 70°F - 5°F = 65°F

at m = 30, T = 70°F - 10°F = 60°F

at m = 45, T = 70°F - 15°F = 55°F

and so on.

Plot  points (0,70), (15,65), (30, 60), (45, 55) and connect them with a straight line. This is the graph that shows the temperature of the room, T, after the window has been open for m minutes.

i pretty sure it is

she was supposed to add the hours(38.5) and multiply the amount of money she earned(7.50) resulting in $288.75 .

correct me if i'm wrong and if it is i'm truly sorry.
