Using a Table of Values to Find a Solution to a System

Mathematics

Answer:

f(x) = 2.5x - 10.5 and g(x) = 64(0.5)^x

When x = 2,

f(x) = 2.5(2) - 10.5 = -5.5,

g(x) = 64 * 0.5^(2) = 16.

When x = 3,

f(x) = 2.5(3) - 10.5 = -3,

g(x) = 64 * 0.5^(3) = 8.

When x = 4,

f(x) = 2.5(4) - 10.5 = -0.5,

g(x) = 64 * 0.5^(4) = 4.

When x = 5,

f(x) = 2.5(5) - 10.5 = 2,

g(x) = 64 * 0.5^(5) = 2.

When x = 6,

f(x) = 2.5(6) - 10.5 = 4.5,

g(x) = 64 * 0.5^(6) = 1.

Therefore we can see that f(x) = g(x) = 2 when x = 5.

Hence the solution is x = 5.

Answer:

This problem wants you to substitute the answers from the table into the equation to find the solution, which is when the input gives the same output basically.

f(x) = 2.5x -10.5                          g(x) = 64(0.5)^x

when x= 2...                                when x= 2...

f(2) = 2.5(2) - 10.5                        g(2) = 64(0.5)^2

f(2) = 5 - 10.5 = -5.5                     g(2) = 64(.25)= 16

when x= 3...                                 when x= 3...

f(3) = 2.5(3) - 10.5                         g(3) = 64(0.5)^3

f(3) = 7.5 - 10.5 = -3                      g(3) = 64(0.125) =8

when x= 4...                               when x = 4...

f(4) = 2.5(4) - 10.5                       g(4) = 64(0.5)^4

f(4) = 10 - 10.5 = -0.5                  g(4) = 64(0.0625) = 4

when x= 5...                               when x= 5...

f(5) = 2.5(5) - 10.5                      g(5) = 64(0.5)^5

f(5) = 12.5 - 10.5 = 2                   g(5) = 64(0.03125) = 2

when x= 6...                               when x = 6...

f(6) = 2.5(6) - 10.5                       g(6) = 64(0.5)^6

f(6) = 15 - 10.5 = 4.5                   g(6) = 64(0.015625) = 1

A stadium has 47000 seats seats sell for $35 in section a $30 in section B and 25 in section c the number of seats in section A
Rainbow [258]

Answer: a section holds 11,750 seats

$1,483,500 from one sold out event

47,000 seats in total, 3 sections (A = B + C)

A = B*2, C*2

47,000 / 4 = 11,750

a movie ticket used to cost $4.25 back in 1990. inflation exist because products increase in value over time. the inflation rate
Andrews [41]

In the year 1998, movie tickets will be greater than $5.50 as determined by solving the equation y=4.25[(1.035)^x].

What is an equation?

  • Math can be used to analyze an equation or a set of equations.
  • An equation is a sentence that maintains the equivalence of two expressions. Most of the time, it is easy to solve the arithmetic equations given in an exact manner.
  • While perfect solutions can occasionally be found, it is more typical to find approaches that are just as accurate. It speaks to the particular guidelines for quadratic mathematical equations.

A movie ticket cost $4.25 in 1990.

The inflation rate is about 3.5%

Rate increased ,r=100%+3.5%=103.5%=1.035

equation generated is,

y=4.25[(1.035)^x]

Solving the equation for each year, we get the following data:

Tabulating the data

Year         cost

1990         4.25

1991          ....

....              ....

1998          5.5964~ 5.6

In the year 1998, the will be greater than $5.50.
