Commutative and Distributive. And also MDAS for basic operations

Commutative Property is the property in which you can move around numbers in numerical operations like, addition and multiplication while retaining their result. In contrast to subtraction and division in which position is an important factor for every result, here it is regardless. Why might you want to use this property?<span>Well, most importantly it suits the operation of addition and hence, to ensure the arrangement of the number is in symmetric proportion to its counterpart such as 3 + 2=2 + 3. Or rather, understanding that the equations in both sides are but the same and equal in sum. Thus, this is much more usable or will make more sense if used in a larger scale of complex equations and integers.<span>

Distributive Property by allotting: 2(3) x 107 = 642<span> </span>

Katyanochek1 [597]

What is x?

It is the number of years since purchase. Can this be negative?

NO! Years cannot be negative. So we disregard negative x-axis.


What is y?

It is the value of the computer at that year. A computer starts off with a positive value (y axis) and depreciates to 0 after some years. Can this be negative?

NO! At 0 value, the computer is worth nothing! There is nothing known as <em>negative </em>value. So we disregard negative y-axis.


The graph that Beth will sketch will have to be in the 1st quadrant (positive x-axis & positive y-axis).

ANSWER: Quadrant I only

A linear function has a slope of 4 and a y-intercept of (0,-8). What is the x-intercept of the line?
miss Akunina [59]

Answer:

The answer to your question is 2 or (2, 0)

Step-by-step explanation:

Data

slope = m = 4

y-intercept = -8

Process

1.- Write the equation of the line in the slope y-intercept

                    y = mx + b

In this equation:

m = slope

b = y-intercept

-Substitution

                   y = 4x - 8

2.- To find the x-intercept, consider that y = 0 and solve for x.

                   0 = 4x - 8

                   4x = 8

                     x = 8/4

                    x = 2    or (2, 0)
