Solve the proportionx+1 14 = x-1 20 a. -3/17 b.10/7 c.7/10 or d. -17/3

x = -17/3

Step-by-step explanation:

x+1 / x-1 = 14/20

20(x + 1) = 14(x - 1)

20x + 20 = 14x - 14

20x - 14x = -14 - 20

6x = -34

x = -34/6

x = -17/3

i use my brain for prombles like this maybe you could try it

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.
