Iam stuck on this question! will give brainliest for the first ! allot of !

miracle solved the following equation:

3 + 2x + 7 = –3x – 9

step
work
justification

1
2x + 3 + 7 = –3x – 9
associative property of addition

2
2x + 10 = –3x – 9
combine like terms

3
5x + 10 = –9
addition property of equality

4
5x = –19
subtraction property of equality

5
x = –3.8
division property of equality

which step has an incorrect justification?

step 4

step 3

step 2

step 1

Step 1

Step-by-step explanation:

Associative property of addition  is  The order of the parentheses.  There are no parentheses is this problem.  We are using the commutative property of addition which states we can change the order of the addends

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
