Tell me all the properties of algebra

Keith_Richards [23]

Answer:

Commutative Property of Addition.-
2 + 3 = 3 + 2

Commutative Property of Multiplication.- ex. 5 × 7 = 7 × 5

Associative Property of Addition.- ex.(2 + 3) + 6 = 2 + (3 + 6)

Associative Property of Multiplication.- ex. (7 × 3) × 10 = 7 × (3 × 10)
Distributive Properties of Addition Over Multiplication- ex. 2 × (2 + 8) = 2 × 2 + 2 × 8
(2 + 8) × 10 = 2 × 10 + 8 × 10

The reciprocal of a non zero real number a is 1/a.- ex. reciprocal of 5 is 1/5 and 5 × (1/5) = 1

Step-by-step explanation:

*Note:

The definition of a derivative is the slope of the tangent line.

Step 1: Define

Identify.

f(-2.4) = -1

f(-1.9) = -8

Step 2: Differentiate

Simply plug in the 2 coordinates into the slope formula to find slope m.

[Derivative] Set up [Slope Formula]: $\displaystyle f'(-2.4) \approx \frac{f(x_2) - f(x_1)}{x_2 - x_1}$
Substitute in coordinates: $\displaystyle f'(-2.4) \approx \frac{-8 - -1}{-1.9 - -2.4}$
Evaluate: $\displaystyle f'(-2.4) \approx -14$
