Solve 7.5y-4.9y

$$7.5 y - 4.9 y$$

Differentiate w.r.t. y

$$2.6$$

Steps Using Definition of a Derivative

Combine 7.5y and -4.9y to get 2.6y.

$$\frac{\mathrm{d}}{\mathrm{d}y}(2.6y)$$

The derivative of ax^{n} is nax^{n-1}.

$$2.6y^{1-1}$$

Subtract 1 from 1.

$$2.6y^{0}$$

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

$$2.6\times 1$$

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

$$2.6$$

Evaluate

$$\frac{13y}{5}$$

Solution Steps

Combine 7.5y and -4.9y to get 2.6y.

$$2.6y$$
