Which property of addition is shown by the equation 6(y+7)=6y+7

None

Step-by-step explanation:

Not only is this multiplication, it is incorrect.

(y + -7)(y + 6) = 0

Reorder the terms:

(-7 + y)(y + 6) = 0

Reorder the terms:

(-7 + y)(6 + y) = 0

Multiply (-7 + y) * (6 + y)

(-7(6 + y) + y(6 + y)) = 0

((6 * -7 + y * -7) + y(6 + y)) = 0

((-42 + -7y) + y(6 + y)) = 0

(-42 + -7y + (6 * y + y * y)) = 0

(-42 + -7y + (6y + y2)) = 0

Combine like terms: -7y + 6y = -1y

(-42 + -1y + y2) = 0

Solving

-42 + -1y + y2 = 0

Solving for variable 'y'.

Factor a trinomial.

(-6 + -1y)(7 + -1y) = 0

Subproblem 1

Set the factor '(-6 + -1y)' equal to zero and attempt to solve:

Simplifying

-6 + -1y = 0

Solving

-6 + -1y = 0

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

21/58.
