Answer:
1) log7 (5*8)= log7(40)
2) log2(11) -log2(9)=log2(11/9)
3)2log9 2=log9(2^2)
5(2x-3)+7
distribute the 5 to the 2x and -3
10x-15+ 7
combine like terms -15+7
10x-8
Time is your independent variable, and snowfall is your dependent variable.
Slope can be found by calculating ∆y/∆x:

Snowfall will accumulate 0.02 m every hour.
