A cell phone plan costs ​$29.80 per month for 800 minutes of talk time. It costs an additional ​$0.07 per minute for each minute over 800 minutes. To get​ e-mail access, it costs 20​% of the price for 800 minutes of talk time. Your​ bill, which includes​ e-mail, is the same each month for 8 months. The total cost for all 8 months is ​$320.80. Write and solve an equation to find the number of minutes of talk time you use each month.

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )

i pretty sure it is

the line of

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.
