The property of a(b+(-b))=(b+(-b))a is called as Commutative Property of Multiplication.

The Commutative Property in mathematics is a rule that allows interchange the order of terms or factors without any change in the end result.

In multiplication, we can interchange the factors without affecting the end result of multiplication. For example, 2 x 3 = 3 x 2 = 6

In addition, we can interchange the terms without affecting the summation result. For example, 2+3 = 3+2 = 5

But Commutative Property does not apply to subtraction or division.

For example, 2-3 != 3-2

or, 2/3 != 3/2

Hence the answer to the question is Commutative Property of Multiplication.

Which equation represents a line that has a slope of 1/3 and passes through point (-2, 1)?
Lorico [155]

Considering the definition of a line, the equation of the line that passes through the point (-2, 1) and has a slope of 1/3 is y= 1/3x + 5/3.

<h3>Linear equation</h3>

A linear equation o line can be expressed in the form y = mx + b

where

  • x and y are coordinates of a point.
  • m is the slope.
  • b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.

<h3>Line in this case</h3>

In this case, you know:

  • The line has a slope of 1/3.
  • The line passes through the point (-2, 1).

Substituting the value of the slope m, you get:

<u><em>y= 1/3x + b</em></u>

Replacing the value of the point in previous expression, the value of the ordinate to the origin b can be obtained:

1= 1/3× (-2) + b

1= - 2/3 + b

1 + 2/3= b

<u><em>5/3= b</em></u>

Finally, the equation of the line is y= 1/3x + 5/3.

Let ​ x² + 15x = 49 .​ What values make an equivalent number sentence after completing the square? Enter your answers in the box
Pavlova-9 [17]

Answer:

Step-by-step explanation:

15/2 = 7.5 and (7.5)^2 = 56.25  so

x^2 + 15x + 56.25 = 49 + 56.25

x^2 + 15x + 56.25 = 105.25.

Given: A = (1, -6) B=(10,-4) Find: squr. 3*AB ​
iragen [17]

Answer:

squr. 39

Step-by-step explanation:

See attached graph.

Form a right triangles and determine the length of the two sides (BC and AC).  Then calculate the hypotenuse (AB) with the Pythagorean Theorem.

AB = 13

I'm not sure what "squr.3AB really means.  3AB is 39.  The square root of 39 is 6.4, if square root is what is meant.
