8y - 4(5 - 6y) + 20

= 8y - 4*5 - 4*(-6y) + 20

= 8y - 4*5 + 24y + 20

= 8y - 20 +24y + 20

= 32y

Hello,

You are talking of the distributivity of multiplication with respect to the addition or subtraction. The only term where you have multiplication and addition/subtraction is the one with parentheses because

4(5-6y) = 4*(5-6y). * means multiply by

Distributing the product consists in removing CORRECTLY the parentheses.

I consider the term alone

4*(5-6y) = 4*5 +4*(-6y)= 20 -4*6*y = 20 -24*y

You put this result in a package and replace it where it was it the original expression.

So

8*y -(package) +20= Replace package

8*y -(20-24*y)+20 = 8*y -20 -(-24y) + 20 Remember -*(-) = +

8*y -20 +24*y +20= Remember -20+20 =0

8*y -20 +20 +24*y= Addition is commutative

8*y +24*y = 32*y

Let y be an orange 8 oranges + 24 oranges =32 oranges.Coclusion

**8y-4(5-8y)+20 = 32y**

First add 2/3 (4/6) + 1/2 (3/6) = (7/6) = 1.1666

6 divided by 1.1666 = 5.1431

6 divided by 1.1666 = 5.1431

Hii,here is list of basic real numbers properties applying them you can solve the problems easily.

Assuming a,b,c,d are real numbers:

**1)Commutative Property **

**a) Property of Addition**: a+b = b+a

**b)Property of Multiplication**: ab = ba

**2)Associative Property **

**a)Property of Addition**: (a+b) + c = a + (b + c)

**b)Property of Multiplication**: ( ab )c = a ( bc )

**3)Additive Identity**:

a+0 = a where 0 is the additive identity

**4)Additive Inverse**:

For real number a, there exists -a such that

a+(-a) = 0

**5)Multiplicative Identity**:

For real number a,

1 X a = a

where 1 is the multiplicative identity

**6)Multiplicative Inverse**:

For real number X where a≠0, there exists 1/asuch that

a X(1/a) = 1

**7)Zero Product Law**:

If ab = 0, then a=0 or b=0 or both a and b = 0.

**8)Distributive Properties**:

**a)Left distributive law**

a (b + c ) = ab + ac

** b)Right distributive law**

(a + b) c = ac+ bc

Assuming a,b,c,d are real numbers:

a+0 = a where 0 is the additive identity

For real number a, there exists -a such that

a+(-a) = 0

For real number a,

1 X a = a

where 1 is the multiplicative identity

For real number X where a≠0, there exists 1/asuch that

a X(1/a) = 1

If ab = 0, then a=0 or b=0 or both a and b = 0.

a (b + c ) = ab + ac

(a + b) c = ac+ bc

I have a samsung french door that was also displaying 88 8Y and found out that it's an error code for the ice maker, I removed the wire cover, disconnected the ice dispencer connector, and then removed the ice dispencer, made sure nothing was stuck inside, plugged in the connector, pushed the reset button, and then put everything back. Unplugged the unit for about 20 min, and when I plugged it back in everything worked. I can't take the credit for this, a thread at applianceguru.com/forum1/8630.html helped me out on this one.

V (2,0) and Focus (2,2)

since the focus is 2 units above the vertex, the parabola opens upward

vertex (h,k)

a is the focal length (distance between the vertex and the focus)

a = 2

(2 units above the vertex)

(x-h)^2 = 4a (y-k)

(x-2)^2 = 4(2) (y-0)

x^2 - 4x + 4 = 8 (y)

x^2 - 4x + 4 = 8y

x^2 - 4x - 8y + 4 = 0

**Answer: "(x-2)^2 = 8 (y)" or in expanded form "x^2 - 4x - 8y +4"
