Can you me ? im not able to fiqure it out

(7^5 * 7^3)^4 * 7^-2 / 7^-7 * 7^20

= (7^8)^4 * 7^-2 / 7^(-7 + 20)

= 7^32 * 7^-2 / 7^13

= 7^(32 - 2) / 7^13

= 7^30 / 7^13

= 7^(30 - 13)

= 7^17

3x + 4y -25 =0 represents the amount of change sianna should recieve

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.
