\frac{\mathrm{d}}{\mathrm{d}x}(-22.5x-47.4)
Combine 11.7x and -34.2x to get -22.5x.
-22.5x^{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}.
-22.5x^{0}
Subtract 1 from 1.
-22.5
For any term t except 0, t^{0}=1.
-22.5x-47.4
Combine 11.7x and -34.2x to get -22.5x.
