Yra solves the equation as shown. - 3(x+2) = 9 1. - 3x - 6 = 9 2. - 3x = 15 3. x = - 5 the property tyra used in line 1 was the:

In line 1 distributive property is used

Step-by-step explanation:

Given equation :

-3(x+2)=9

Tyra solves it as :

1. -3x-6=9

2. -3x=15

3. x=-5

In 1. Distributive property is used i.e.

2. Addition property is used

i.e.If a=b then a+c=b+c

3. Division property is used

i.e. If a=b then

=

Therefore the property used in line 1 is :

Distributive property

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!

step-by-step explanation:

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen
