Based on the number of movies, $12.75 is the constant of proportionality per movie
How to determine the constant of proportionality?The given parameters are
Number of the movie tickets = 6
Cost of the movie tickets = 76.50
The constant of proportionality of the movie tickets is calculated as
Constant of proportionality = Cost of the movie tickets/Number of the movie tickets
Substitute the known values in the above equation
So, we have
Constant of proportionality = 76.50/6
Evaluate the quotient
So, we have
Constant of proportionality = 12.75
Hence, the constant of proportionality per movie is $12.75

Determine the slope of the function as a unit rate for the linear situation. y = − 4 4/5x + 13 1/2
The slope of the function as a unit rate for the linear situation. y = [tex]-4\frac{4}{5}[/tex]x + [tex]13\frac{1}{2}[/tex] can be viewed as [tex]-4\frac{4}{5}[/tex] by taking the derivative of the first term of the equation.
What is the slope of a function?The slope m=y/x of a straight-line y=mx+b quantifies the change in y for every unit change in x. This can also be interpreted as a kind of measure of "sensitivity''.
Finding the slope of a function is like finding the rate at which the value of y (the dependent variable) changes in relation to x is what this method entails (independent variable).
How to find the slope of a function?To find the slope of a line that is given with the equation of the line, first you have to write the equation of the line in a slope-intercept form.
Then use inverse operations in order to solve for y so that it is written as y=mx+b. Thereafter you can easily spot the slope since the slope is the coefficient of the x variable, or in other words, the number in front of x.

Step-by-step explanation:
In AJKL, JL is extended through point L to point M,
m/JKL = (3x – 16)°, m/LJK = (2x + 15)°, and
m/KLM = (8x – 19)°. Find m/LJK.
The value of x is 6 and the measure of angle LJK is 27°.
According to the triangle's "angle sum property," a triangle's interior angles add up to 180°.
We have the measure of the following angles,
m∠JKL = ( 3x - 16 )°
m∠LJK = ( 2x + 15 )°
m∠KLM = ( 8x - 19)°
In ΔJKL, JL is extended through point L to point M.
At point L, the measure of angle JLK will be as,
m∠KLM + m∠JLK = 180°
m∠JLK = 180° - m∠KLM
m∠JLK = 180° - ( 8x - 19)°
m∠JLK = ( 199 - 8x )°
Now,
In triangle JKL,
By angle sum property:
m∠JKL + m∠LJK + m∠JLK = 180°
(3x – 16)° + (2x + 15)° + ( 199 - 8x )° = 180°
- 3x + 198 = 180
- 3x = - 18
x = 6°
Therefore,
m∠LJK = ( 2x + 15 )°
m∠LJK = ( 2(6) + 15 )°
m∠LJK = ( 12 + 15 )°
m∠LJK = 27°
The measure of angle LJK is 27°.

let f(x)=x^2+3x and g(x)=2x-1 find each function value f(g(-2))
The composite result function of f( g(-2) ) in the given functions f( x ) = x² + 3x and g( x ) = 2x - 1 is 10.
What is the composite result function of f( g(-2) ) in the given function?A function is simply a relationship that maps one input to one output..
Given the data in the question;
f( x ) = x² + 3xg( x ) = 2x - 1f( g(-2) ) = ?First, set up the composite result function f( g(x) )
f( x ) = x² + 3x
f( g(x) ) = f( 2x - 1 ) = ( 2x - 1 )² + 3( 2x - 1 )
f( g(x) ) = ( 2x - 1 )² + 3( 2x - 1 )
Simplify
f( g(x) ) = ( 2x - 1 )( 2x - 1 ) + 3( 2x - 1 )
f( g(x) ) = 2x( 2x - 1 ) -1(2x - 1 ) + 3( 2x - 1 )
f( g(x) ) = ( 4x² - 2x - 2x + 1 ) + 3( 2x - 1 )
f( g(x) ) = ( 4x² - 4x + 1 ) + 6x - 3
f( g(x) ) = 4x² - 4x + 1 - 6x - 3
f( g(x) ) = 4x² - 4x + 6x + 1 - 3
f( g(x) ) = 4x² + 2x - 2
Now, replace all the occurrence of x with -2 in the function and simplify.
f( g(-2) ) = 4(-2)² + 2(-2) - 2
f( g(-2) ) = 4×4 - 4 - 2
f( g(-2) ) = 16 - 4 - 2
f( g(-2) ) = 10
The composite result function of f( g(-2) ) in the given functions is 10.

Drag each object to show whether distance is proportional to time in the situation represented.
The table with the situations that represent or not proportional relationships of distance and time is given at the end of the answer.
Which situation models a proportional relationship?A situation represents a proportional relationship if the output variable y in the y-axis is written as a product of the input variable x in the x-axis and the constant of proportionality k, as follows:
y = kx.
One example, in the context of this problem, is the relation between velocity, distance and time, as velocity is distance divided by time, hence:
v = d/t.
The relation between distance and time is given as follows:
distance = velocity x time
distance = v x t.
Hence it will only be proportional if the velocity is constant, that is, if the acceleration is of zero.
Examples of non-proportional situations in the context of this problem are:
A touchdown, as when the play starts the player is stopped then he accelerates and the velocity is not constant.The horse running around the race track, same logic, different velocities.The distance and time table (4 - 15, 8 - 30, 12 - 45) does not show enough information, we need to know if the initial point was of (0,0).

Step-by-step explanation:
we sadly need to do all the multiplications for the whole polynomial in standard form.
the other 3 things we get out of the given form :
we multiply 3 terms, each in x. the result will be x³.
so, we have the 3rd degree.
the leading coefficient is 1, as for the x³ term we get x×x×x = x³. no other number is involved.
the constant term is the extreme on the other end. it is 4×2×1 = 8.
so, now for the full multiplications, that should also show you, why I could make the conclusions above.
(x+4)(x-2)(x+1)
we do this by multiplying first 2 terms with each other, and then we multiply that result by the third term.
remember, we need to multiply every item of one term with every item in the other term.
(x+4)(x-2) = x² -2x + 4x - 8 = x² + 2x - 8
now
(x² + 2x - 8)(x+1) = x³ + x² + 2x² + 2x - 8x - 8 =
= x³ + 3x² - 6x - 8
so, that is already the standard form
f(x) = x³ + 3x² - 6x - 8

Alternate angles are angles that occur on opposite sides of the transversal line and have the same size.
Both are obtuse angles and are on the opposite side of the transversal line
Answer:
∠KLC is the alternate angle of ∠BKL
Step-by-step explanation:
Alternate angles are angles that are opposite of one another and on two different parallel lines created by an intersecting line (also known as a transverse line).
In this case, the parallel lines are lines A↔B and C↔D, and the transverse line is M↔N. Therefore, the alternate angle from ∠BKL is ∠KLC.
write the equation in slope intercept form of the line that passes through the points (-4,8) and (4,6)
The equation of the line in the slope-intercept form is y = -1/4x + 9
Equation of a lineFrom the question, we are to determine the equation of the line that passes through the given points.
The given points are (-4, 8) and (4, 6)
Using the formula,
(y - y₁)/(x - x₁) = (y₂ - y₁)/(x₂ - x₁)
x₁ = -4
y₁ = 8
x₂ = 4
y₂ = 6
Thus,
(y - 8)/(x - -4) = (6 - 8)/(4 - -4)
(y - 8)/(x + 4) = -2 / (4 + 4)
(y - 8)/(x + 4) = -2 / 8
(y - 8)/(x + 4) = -1/4
4(y - 8) = -1(x + 4)
4(y - 8) = -x + 4
y - 8 = -1/4x + 1
y = -1/4x + 1 + 8
y = -1/4x + 9
Therefore,
The equation is y = -1/4x + 9

which of the following options result in a graph that shows expoential decay
The option that results in a graph that shows exponential decay is Option(b) f(x) = 3(0.7)ˣ.
What is the Exponential Decay Formula?The exponential decay formula helps to determine the rapid decline over time or exponential decline. The exponential decay formula is used to calculate various types of decay, including radioactivity decay, half-life, and population decay.The exponential decay formula is f(x) = abˣ, where a is the initial amount, b is the decay factor and x is the time interval.According to the question, we have to determine the function that results in a graph that shows exponential decay.
The function will show an exponential decay if the value of b was less than 1 and greater than 0.
As we can notice in the second option, f(x) = 3(0.7)ˣ, where b is equal to 0.7 which is less than one.
So, f(x) = 3(0.7)ˣ shows exponential decay.
