Which expressions are equivalent to -2y-8+4y

C.) None of the above

Step-by-step explanation:

2y - 8 + 4y​

Combine like terms

2y and 4y

6y - 8

Now all we need to do is answer the other ones

-2( y + 4 ) + 4y

Distributive property

-2y - 8 + 4y

Combine like terms

2y - 8 INCORRECT

4 ( -2 + y ) - 2y

Distributive property

-8 + 4y - 2y

Combine like terms

2y - 8 INCORRECT

So the correct answer is C none of the above.

Hope this helped!

Have a day!

idk

step-by-step explanation:

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

the factor is 2

step-by-step explanation:

let f(x)=8(3^(x−2)+2)

to stretch a graph by 3, it would be 3f(x)

g(x) =3f(x)

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

x     −2     0     2     4     6

f(x) 1/64 1/16   1/4     1     4

1/64 * z * z = 1/16

i multiplies by z twice because it its 2 steps from -2 to 0

1/64 z^2 = 1/16

multiply by 64 to clear the fraction on the left side

1/4 * 64 z^2 =1/16 *64

z^2 = 4

take the square root of each side

sqrt(z^2) = ±sqrt(4)

z = ±2  

we are multiplying by 2 each time.
