Solve (2.25*0.40)+(x*0.60)

$$(2.25 \times 0.40)+(x \times 0.60)$$

Differentiate w.r.t. x

$$0.6$$

Steps Using Derivative Rule for Sum

Multiply 2.25 and 0.4 to get 0.9.

$$\frac{\mathrm{d}}{\mathrm{d}x}(0.9+x\times 0.6)$$

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}.

$$0.6x^{1-1}$$

Subtract 1 from 1.

$$0.6x^{0}$$

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

$$0.6\times 1$$

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

$$0.6$$

Evaluate

$$\frac{3x}{5}+0.9$$

Solution Steps

Multiply 2.25 and 0.4 to get 0.9.

$$0.9+x\times 0.6$$
