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.

3x - 4y =  - 6 \\  - 2x + y = 1

<em>The Ordered pair of solution will be (x,y)=(2,3)</em>

\red{ \rule{35pt}{2pt}} \orange{ \rule{35pt}{2pt}} \color{yellow}{ \rule{35pt} {2pt}} \green{ \rule{35pt} {2pt}} \blue{ \rule{35pt} {2pt}} \purple{ \rule{35pt} {2pt}}

<h3>Steps below⤵️</h3>

  • Solve the second equation for y
  • Substitute the given value of y into the first equation
  • Solve the first equation for x
  • Substitute the given value of x into the second equation
  • Solve the equation for y
  • The possible solution of the system is the ordered pair (x,y)
  • And we are done solving!!~

Which best represents the units of the average rate of change for the boiling point based on the amounts of ethylene glycol in t
mario62 [17]

Answer:

Option b. degrees Fahrenheit/(mililiters)

Step-by-step explanation:

we know that

The formula to calculate the average rate of change between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have  that

the units of the y-axis are {\°F}

the units of the x-axis are {ml}

therefore

the units of the the average rate of change are

m=\frac{\°F}{ml}
