20.9, rounded 21 miles

Step-by-step explanation:

x= distance between the airport and Ann's home.

since Ann is paying $2.10 per mile let 2.10 be the coefficient

our equation:

5 is our constant since that's how much Ann trips the driver

since the total is equal to 49.10, that's what our equation will be equal to

2.10x+5=49.10

sub "5"

2.10x+5-5=49.10-5

2.10x=44

divide both sides by "2.10"

2.10/2.10x=44/2.10

x=20.9

we can round 20.9 to 21

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.
