Yaritza had 2 inches of snow on her lawn. It then began to snow at a rate of 2 inches per hour. Assume no snow melted. Answer the questions below regarding the relationship between the number of hours since snow began falling and the total amount of snow on Yaritza's lawn.
The independent variable, x, represents the hours since it started snowing, and the dependent variable is the inches of snow on the ground, because the hours since it started snowing depends on the inches of snow on the ground.
A function relating these variables is T(x)= blank*.
So T(10)= blank*, after 10
-inches of snow have fallen, it has been snowing for
-hours of snowing there will be
blank*
-hours
-inches of snow on the lawn
.
T(x) = 2 + 2x
T(10) = 2 + 2(10) = 22
So after 10 hours of snowing, there will be 22 inches of snow on the lawn.
