Which statement best reflects the solution(s) of the equation?

a. there is only one solution: x = 1. the solution x = 2 is an extraneous solution.

b. there is only one solution: x = 2. the solution x = 0 is an extraneous solution.

c. there is only one solution: x = 2. the solution x = 1 is an extraneous solution.

d. there are two solutions: x = 1 and x = 2.

C. There is only one solution: . The solution is an extraneous solution.

Step-by-step explanation:

Given:

The equation is:

Now, we solve this quadratic equation by factoring.

Now, is an extraneous solution as at equal to 1, the equation is undefined.

Therefore, is the only solution. The solution is an extraneous solution.

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

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.
