Question

Name the property of real numbers illustrated by the equation.
-4(x+3)=-4x-12

A. Commutative Property of Addition
B. Associative Property of Addition
C. Distributive Property
D. Associative Property of Multiplication

Answer 1

is this for homework?

Answer 2

or a quiz/test?

Answer 3

homework. its algebra two. and i just dont understand anything about it

Answer 4

maybe it was because emily had nothing better to do on friday night than make up a question to post here

Answer 5

WAITT, are you sure this is algebra 2. This seems pretty basic.

Answer 6

@EmilyJernigan when you remove parentheses by multiplication, you use the distributive law (property)

Answer 7

^^is true but the associative property also involved parentheses :/

Answer 8

Positive! I can do almost anything but math!

Answer 9

this says \(a(b+c)=ab+ac\) so in your example you have \[-4(x+3)=-4\times x+(-4)\times 3=-4x-12\]

Answer 10

why do you explain so much....

Answer 11

have nothing better to do on a friday night bwah xd

Answer 12

ohhh! got it. :)

Answer 13

good
btw the distributive law is very important to remember because it links multiplication and addition
it is also the one that is easiest to forget when doing other math problems

Answer 14

Its been a while since ive done any math. And all my classes are online now. And i dont have any one to teach me. i gotta self teach. but all i have left is this class! but thank you. i got a couple more on this assignment

Answer 15

go ahead and post. i promise not to ask "is this a homework"

Answer 16

Solve the inequality. Graph the solution.
2|x+1/3|<9

Answer 17

ick

Answer 18

this is going to take some work with fractions
first divide both sides by 2 to get
\[|x+\frac{1}{3}|<\frac{9}{2}\]

Answer 19

then remove the parentheses and make a compound inequality
\[-\frac{9}{2}<x+\frac{1}{3}<\frac{9}{2}\]

Answer 20

then subtract \(\frac{1}{3}\) straight across to get
\[-\frac{29}{6}<x<\frac{25}{6}\]

Answer 21

okay. then i simplify?

Answer 22

well there is nothing to simplify
neither of the fractions reduce

Answer 23

none of my answers look like that....? :/

Answer 24

are you sure you copied the question down exactly right?

Answer 25

they look something like this.. this is answer A
