Write the equation for this situation:

During the month of January, the depth, d, of snow in inches at the base of one ski resort could be approximated by adding 5 to twice the number of days, t, since December 31st.

Then graph the equation and use the graph to determine the depth of the snow on January 15.

Please show all of your work.

anonymous · Answer

This is the equation:
d = 2t + 5
Graph it in a (t, d) coordinate system. To get the depth of the snow, read the d-value from t=15.
