Is the sum of two polynomials of degree n always a polynomial of degree n? Why or why not?

1 answer:

4 0

Supposing the coefficients of the degree n terms are negatives of one another. Then the sum of the nth degree terms is zero, and the resulting polynomal is not of degree n.

What is the rate of change of the following equation? y = 5x + 4

almond37 [142]

Answer:

Step-by-step explanation:

Rate of change of the equation y = 5x + 4 can be obtained by differentiating it with respect to x.

$\because \: y = 5x + 4 \\ \therefore \: \frac{dy}{dx} = \frac{d}{dx} (5x + 4) \\ \\ = 5 \frac{d}{dx} x + \frac{d}{dx} 4 \\ \\ = 5 \times 1 + 0 \\ \therefore \: \frac{dy}{dx} = 5 \\$
