Lots of points and will give
which sequence is modeled by the graph below? coordinate plane showing the points 1, 1; 2, 3; 3, 9

an = 3^(n-1)

Step-by-step explanation:

(1,1)  (2,3)  (3,9)

The y values

1,3,9,

We are multiplying by 3 each time

This is a geometric sequence

The formula for a geometric sequence is

an = a1 (r) ^ (n-1)

 where a1 is the first term  r is the common ratio ( or what we multiply by) and n is the term number

a1 = 1

r =3

an = 1* (3) ^ (n-1)

an = 3^(n-1)

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i
