Answer:
2nd option is the correct answer
Step-by-step explanation:

Answer:
This does represent an exponential function , because his savings increase by a constant rate
Step-by-step explanation:
Let
x -----> the number of weeks
y ----> the amount saved
In this problem we have a exponential function of the form

where
a is the initial value
b is the base
r is the rate of change
where

---- because he doubles the amount each week
----> 
substitute

therefore
This does represent an exponential function , because his savings increase by a constant rate
Answer:
t = 2.58333
Step-by-step explanation:
use the distributive property:
200 = 16(6t - 3)
multiply the 16 to each value in the parenthesis:
200 = 96t - 48
now add 48 to both sides:
200 = 96t - 48
+48 + 48
248 = 96t
now divide each side by 96:
248/96 = 96t/96
t = 2.583333
decimal form: 2.5833333
mixed number: 
2.5euros/1kg×?U.S$/?euro×1kg/?lb
and, 1 kg=2.20462 lb
2.5/1 * $1.256/.7965 E * 1KG/2.204 =3.14/178= 1.76.
Answer:
D. 9 meters
Step-by-step explanation:
AB = CD, so 9x-27=2x+1.
If you get like terms on the same side you get 7x=28
If you simplify by dividing everything by 7, you get x=4
If you plug 4 in as x into the expression 2x+1, you get 9.
