Question: What is the commutative, associative, and distributive property of 3a plus 5a plus 2b0.

Answer:Defintion of Commutative property holds for both addition and multiplication. That is: the operations addition and multiplication are commutative over the set of real numbers. That means, for any two real numbers x and. y, x + y = y + x and xy = yx. Definiton of associative In mathematics, the associative property is a property of some binary operations. In propositional logic, associativity is a valid rule of replacement for expressions in logical proofs and distrive property means The Distributive Property is an algebra property which is used to multiply a single term and two or more terms inside a set of parentheses. I really hope this helped thx for the question!

Commutative: a+b=b+a
associative: (a+b)+c=a+(b+c)
distributive: ab+ac=a(b+c)

so
3a+5a+2b
we can show distributive with the a terms
3a+5a=a(3+5)=8a
8a+2b
we can distribute again
2(4a)+2b=2(4a+b)

not sure how to show commutative or associative
I guess
3a+5a+2b=2b+3a+5a

Skyler goes to a school which has 100 students in it. She asks 40 random students whether they like the new 8.30 am start to the

dybincka [34]

Answer:

75 students

Step-by-step explanation:

first write a ratio of the students asked to students dislike

40:30, 40 to 30, or 40/30

now simplify the ratio

4/3

now she asked 40 students, so we have to find out the unit rate

so we have to flip the fraction to 3/4 and then divided the top and bottom by 4

0.75/1

now multiply the top and bottom by 100

75/100

75 students

What is a point-slope equation of the line with slope -10 that goes through the point (1,4)

KatRina [158]

$\bf (\stackrel{x_1}{1}~,~\stackrel{y_1}{4})\qquad \qquad \qquad 
% slope = m
slope = m\implies -10
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-4=-10(x-1)$

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s). Line m has no y

goblinko [34]

If the line does not have a y int, then it means it does not cross the y axis....that means it is a vertical line.....its x int is (3,0)...so this equation for the line is x = 3

if the line does not have an x int, it means it does not cross the x axis...that means it is a horizontal line...its y int is (0,-4)...so the equation for this line is
y = -4
