$$\frac{\mathrm{d}}{\mathrm{d}x}(20x-13)$$

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}.

$$20x^{1-1}$$

Subtract 1 from 1.

$$20x^{0}$$

For any term t except 0, t^{0}=1.

$$20\times 1$$

For any term t, t\times 1=t and 1t=t.

$$20$$

Evaluate

$$20x-13$$

Solution Steps
