The number of pennies is an illustration of pattern and sequence.

The number of pennies in the nth square is 2^{n-1

From the complete question, we have the following parameters

f(1) =1

f(2) =2

f(3) =4

f(4) =8

Rewrite the functions as follows:

f(1) = 2^0

f(2) = 2^1

f(3) = 2^2

f(4) = 2^3

Express 3 as 4 - 1

f(4) = 2^{4-1

Replace 4 with n

f(n) = 2^{n-1

Hence, the number of pennies in the nth square is 2^{n-1

Answer:

The solution of the system is

x=8, y=11

Step-by-step explanation:

we have

y = 2x-5 ----> equation A

y = x+3 ----> equation B

Solve the system by graphing

Remember that the solution of the system of equations is the intersection point both graphs

using a graphing tool

The intersection point is (8,11)

see the attached figure

therefore

The solution of the system is

x=8, y=11

3. Connie bought several types of candy for Halloween: Milky Ways, Tootsie Rolls,
devlian [24]

Answer:

Tootsie Rolls = 13

Step-by-step explanation:

Given:

Milky Ways and Tootsie Rolls together were 15 more than the number of Reese's Cups.

There were 4 fewer Reese's Cups than Hershey Bars.

There were 12 Milky Ways and 14 Hershey Bars.

Solution

Milky Ways and Tootsie Rolls = Reese's Cups + 15

There were 4 fewer Reese's Cups than Hershey Bars.

Hershey Bars = 14

Then,

Reese's Cups = 14 - 4

= 10

Milky ways = 12

Hershey bars = 14

Reese's Cups = 10

Milky ways = 12

Milky Ways + Tootsie Rolls = Reese's Cups + 15

12 + Tootsie Rolls = 10 + 15

12 + Tootsie Rolls = 25

Subtract 12 from both sides

Tootsie Rolls = 25 - 12

= 13

Tootsie Rolls = 13
