You've determined that, in a direct variation problem, the constant of variation (k) is 1/8. what is the value of y when x is 12? just type the value of y (a number). if it's an integer, type the integer. otherwise, write it as a fraction in simplest form.

ANSWER

When the value of x is 12, then,

EXPLANATION

The statement, y varies directly as x is written nathematically as

If we introduce the constant of proportionality, then we can write the equation,

where k is the constant of proportionality. It is also called the constant of variation.

If

, then the direct variation equation becomes.

When

, then

This simplifies to

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.

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.
