Answer:
3
Step-by-step explanation:
Exponential equation:
An exponential equation has the following format:

In which a is the value of y when x = 0.
In this question:
When
. Thus, we have that a = 3.
They both use the intercections of arcs to find the line. I think.
Answer:
G.
Step-by-step explanation:
cards = 2
dollars = 9
to check that the number of cards with the correct amount d;
use the ratio and proportion.
(3 x 18)/9 = 4
(4 x 31.5)/18 = 7
(7 x 45)/31.5 = 10
therefore, option G. table G. is the correct answer
try doing the ratio and proportion on the other table and the number of cards DO NOT match with the amount. (see attached)
