A(1) = -2 x 5(1) - 1 = -11
A(4) = -2 x 5(4) -1 = -41
A(8) = -2 x 5(8) -1 = -81
Answer:
The cost of one bag of diapers is $11 and the cost of one can of formula is $13
Step-by-step explanation:
Let
x -----> the cost of one bag of diapers
y ----> the cost of one can of formula
we know that
-----> equation A
----> equation B
Solve the system by graphing
Remember that the solution of the system is the intersection point both graphs
The solution is the point (11,13)
see the attached figure
therefore
The cost of one bag of diapers is $11 and the cost of one can of formula is $13
Umm.. I think I'll be 2,926 you coulda got on a calculator and get your answer.
This sequence of numbers works because each time it is multiplied by 2.
(2x2=4 4x2=8 8x2=16) etc...
In conclusion each number is multiplied by 2 in the sequence.
The area of the rectangle would be 45 m^3
