\frac{\mathrm{d}}{\mathrm{d}m}(9-20m)
Combine -10m and -10m to get -20m.
-20m^{1-1}
The derivative of a polynomial is the sum of the derivatives of its terms. The derivative of a constant term is 0. The derivative of ax^{n} is nax^{n-1}.
-20m^{0}
Subtract 1 from 1.
-20
For any term t except 0, t^{0}=1.
9-20m
Combine -10m and -10m to get -20m.
