3(y - 3) = -15
I really need help

y=-2

Step-by-step explanation:

can i get brainliest please???

it would be very much appreciated

have a nice day :)

y=-2

Step-by-step explanation:

3(y-3)=-15

Divide both sides by 3:

3(y-3)/3=-15/3

Simplify:

3(y-3)/3=-15/3

3(y-3)/3

Divide the numbers:3/3=1

=y-3

Simplify:

-15/3

Divide the numbers:15/3=5

=-5

y-3=-5

Add 3 to both sides:

y-3+3=-5+3

Simplify:

y=-2

i think the answer is d im not sure

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.
