The word "commutative" comes from "commute" or "move around", so the Commutative Property is the one that refers to moving stuff around. For addition, the rule is "a+b=b+a"; in numbers, this means 2+3=3+2. For multiplication, the rule is "ab=ba"; in numbers, this means 2x3=3x2.

The commutative property of addition means that when you see a problem, you change the order. The co in commutative means change order. That's what my teacher told me.

What's the value of this python expression: (2**2) == 4?

vfiekz [6]

Answer:

Python will return:

True

Step-by-step explanation:

The math function ** is an exponent indicator.

The equation you made was:
$2^2 =4$

When you run this in python, it will return as true.

It is run as a Boolean expression because you have already provided the answer to the expression with the "==" statement.

If you had provided an incorrect answer (setting it equal to any number other than 4), it would return False.

write an equation in point slope form of the line that passes through the point (5/6 , 0) and has a slope of m=-3

lyudmila [28]

$(\stackrel{x_1}{\frac{5}{6}}~,~\stackrel{y_1}{0})~\hspace{10em} \stackrel{slope}{m}\implies -3 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{0}=\stackrel{m}{-3}(x-\stackrel{x_1}{\frac{5}{6}})$
