Based on the linear relationship between the ticket numbers and the total cost, the cost of one ticket can be found to be A. $10.50

First, find the rate of change in ticket pricing assuming the number of tickets is x and the total cost is y.

The rate of change is:

= Change in y / Change in x

= (67.50 - 46.50) / (5 - 3)

= $10.50

Then find the y-intercept:

y = Slope(x) + y-intercept

67.50 = 10.50(5) + y-intercept

y-intercept  = 67.50 - 52.50

y-intercept = 15

Linear equation is:

Total cost = Rate of change (Tickets) + y-intercept

A single ticket would cost $10.50 which is the rate of change.

The required rate of change and slope of the given relationship is $10.50.

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,
The slope for the linear function is given as,
m = (y₂ - y₁) /  (x₂ - x₁)

From the table substitute the value in the above equation,
m = [67.50-46.50]/[5-3]
m = 21 / 2
m = 10.50

Thus, the required rate of change and slope of the given relationship is $10.50.

Answer:

AD

Step-by-step explanation:

It is not possible to write a linear inequality such that the solution contains only positive values of x and y.

This happens because every line on the coordinate plane must have a y-intercept and/or an x-intercept. When the line crosses an axis, either the variable x or y changes its sign.

Answer:

(4,-5)

Step-by-step explanation:

A is 5 units above the x axis so a' will be 5 units below the x axis.

We will determine the area of the green section as follows:

Here alpha is the angle [In radians] and r is the radius-

*First: We determine the angle:

Now, we transform it to radians:

*Second: We replace on the equation:

So, the area of the green sector is 69pi/5 square centimeters. [Approximately 43.4 square centimeters]

Answer:

A ≈ 43.4 cm²

Step-by-step explanation:

the area (A) of the green sector is calculated as

A = area of circle × fraction of circle

  given d = 12 then r = 12 ÷ 2 = 6 cm

the central angle of the green sector = 180° - 42° = 138°

then

A = πr² × [tex]\frac{138}{360}[/tex] ( simplify fraction by dividing numerator/denominator by 6 )

   = π × 6² × [tex]\frac{23}{60}[/tex]

   = 36π × [tex]\frac{23}{60}[/tex]

   = [tex]\frac{36\\pi (23) }{60}[/tex]

   ≈ 43.4 cm² ( to the nearest tenth )

In terms of the calculation, the answer is 39/4 in improper fraction.

An improper fraction has a denominator that is greater than or equal to the numerator. Based on the numerator and denominator values, proper fractions and improper fractions are the two main types of fractions in mathematics.

A mixed fraction is a fraction formed by combining a natural number and a proper fraction. It is a shortened version of an improper fraction.

The given equation is [tex]3\frac{1}{4}[/tex] + [tex]6\frac{1}{2}[/tex] .

Taking 4 as LCM from the above equation.

[tex]3\frac{1}{4}[/tex] + [tex]6\frac{1}{2}[/tex] = (13/4) + (13/2)

[tex]3\frac{1}{4}[/tex] + [tex]6\frac{1}{2}[/tex] = (13+26)/4

[tex]3\frac{1}{4}[/tex] + [tex]6\frac{1}{2}[/tex] = 39/4

Each midpoint's coordinate is given by the mean of the respective coordinates of the two endpoints of the segment. Then, if we say M is the midpoint of that segment, we have:

Mx = (-4 + 4)/2 = 0/2 = 0

My = [6 + (-2)]/2 = (6 - 2)/2 = 4/2 = 2

Therefore, writing those coordinates as an ordered pair, we have:

M = (0, 2)

If the coordinates of quadrilateral ABCD are A (-6,2) B (-5,3) C (7,3) D (0,4) and it is translated 4 units down and 3 units right, then the coordinates of the image is A'(-3,-2), B'(-2,-1), C'(10,-1) and D'(3,0)

The coordinates of the quadrilateral ABCD is

A (-6,2) , B(-5,3), C(7,3) and D(0,4)

The quadrilateral is translated 4 units down and 3 units right

After translation

A(x, y)⇒ A(x + a, y +b)

The value of a and b will be positive if the shift is right and up.

The value of a and b will be negative if the shift is left and down.

Therefore

a = 3, b = -4

The coordinates of A' =(-6+3,2-4)=(-3,-2)

The coordinates of B' =(-5+3,3-4)=(-2,-1)

The coordinates of C' =(7+3,3-4)=(10,-1)

The coordinates of D' =(0+3,4-4)=(3,0)

Hence, If the coordinates of quadrilateral ABCD are A (-6,2) B (-5,3) C (7,3) D (0,4) and it is translated 4 units down and 3 units right, then the coordinates of the image is A'(-3, -2), B'(-2, -1), C'(10, -1) and D'(3, 0)

The sum of  -1  and 3/4 and 2 and 1/2 is the same as the difference between 2 and 1/2 and 1 and 3/4.

First we will convert the mixed fractions into improper fractions.

-1 and 3/4 = -7/4

2 and 1/2 = 5/2

Sum of -1 and 3/4 and 2 and 1/2 = -7/4 + 5/2 = -7/4 + 10/4 = 3/4

Difference between  2 and 1/2 and 1 and 3/4 = 5/2 - 7/4 = 10/4 - 7/4 = 3/4

The value of g(a) + h(a) is a²-3a-2 or (a-2)(a-1) using addition of functions.

Given a collection of inputs X (domain) and a set of potential outputs Y (codomain), a function is more technically defined as a set of ordered pairings (x,y) where x belongs to X  and y belongs to Y, with the caveat that there can only be one ordered pair with the same value of x. The function notation f:XY can be used to express that f is a function from X to Y

Adding two functions-

g(a) = a²- 2

h(a) = -3a

Let h(a) be g(a) + h(a)

So h(a) = a² - 2 - 3a.

We can factorize the function into (a-2)(a-1).

So we get h(a) = (a-2)(a-1).

The equation for constant proportionality is y ∝ m .

1760 is a constant of proportionality.

The ratio of two proportional values at a constant value is the proportionality constant. When either the ratio or the product of two variables results in a constant, the connection between the two is proportional. The ratio between the two stated quantities affects the proportionality constant's value.

The formula y = 1760m describes the relationship between a distance in yards (y) and a similar value in miles (m).

As a result, the graph of the aforementioned equation will be a straight line with a constant slope of 1760 that passes through the origin (0, 0).

As a result, a measurement in yards and a measurement in miles have the same proportionality relationship.

The amount of coffee she bought is 5.16 pounds.

She received a $70 gift card for a coffee store.

Therefore, base on the card, the number of pounds of coffee she bought can be calculated as follows;

Hence,

let

the amount of coffee she bought in pounds = x

Hence,

70 = 8.36x + 26.85

70  - 26.85 = 8.36x

43.15 = 8.36x

The figure above is a rectangle

The classifications of a rectangle are:

1. A rectangle has 4 sides and angles, therefore, it is a quadrilateral.

2. Each interior angle is a right-angle, that is 90⁰

3. The sum of the interior angles equals 360

4. The opposite sides are parallel

5. The opposite sides are equal

6. The diagonals bisect each other

7. The diagonals have the same length

By the concept of measurement of length we get the remaining length of the pipe 65 cm.

The total length of pipe before it was used by the plumber was 2.5 metre = (2.5 x 100)cm = 250cm.

Since,the plumber needs to cut lengths of 60cm, 35cm and 90cm

Thus,total Length of the pipe cut  by the plumber = 60cm + 35cm + 90cm = 185cm

After subtracting the length of pipe used by the plumber from the original length of the pipe, we get,

The remaining length of the pipe = 250 - 185 = 65cm

Hence, the remaining length of the pipe is 65 cm.

Question 4

Answer: Alternative C - 0

Step-by-step explanation:

Since x→∞, we can substitute the values of x for values as 10, 100, 1000 and see the tendency of the function when the values are getting higher (closer to ∞):

For x = 10

f(10) = 0.5*10^(-3/4)

f(10) = 0.089

For x = 100

f(10) = 0.5*100^(-3/4)

f(10) = 0.016

For x = 1000

f(10) = 0.5*1000^(-3/4)

f(10) = 0.003

As we can see, when the x-values are getting closer to infinite, the y-values tends to zero. Thus, alternative C is correct.

Given:

1. The sum of X and 96 equals half of X.

To determine the algebraic equation, we note that the sum of x and 96 would be:
