There is no slope, hence the equation of the line will be in the form y = b. Then the equation of the line that is perpendicular to the given line and passes through the point (1, 5) exists (A) y = 5.
What is meant by equation?The definition of an equation in algebra exists as a mathematical statement that demonstrates the equality of two mathematical expressions.The equation of a perpendicular line to a line in point-slope form is expressed as:
y - y1 = -1/m(x - x1)m is the slope(x1, y1) is any point on the lineDetermine the slope:
Slope = -3-3/2-2y = ∞Since there is no slope, hence the equation of the line will be in the form y = b.
Where b exists the y-coordinate of the point. Hence the required equation of the line is y = 5Therefore, there is no slope, hence the equation of the line will be in the form y = b. Then the equation of the line that is perpendicular to the given line and passes through the point (1, 5) exists (A) y = 5.

A local movie theater sells tickets at different prices for an adult and for a child. The price of an adult’s ticket is $10.50 and the price of a child’s ticket is $6.50 . If the theater sells a total of 65 tickets for a total price of $594.50 in an afternoon, how many child tickets did the theater sell?
Answer:
6.50 × 65 tickets.
Answer = $422.5
The theater sells 43 adult tickets and 22 child tickets.
What is an equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Let us assume,
The number of adult tickets sold is x
The number of tickets sold for children is y
Since the total number of tickets sold is 65,
x + y = 65 .....(i)
Charge per adult ticket=$10.50,
So the amount collected by selling adult tickets is 10.50×x
Charge per child ticket=$6.50,
So the amount collected by selling tickets for children is 6.50×y
We know that the total amount earned by the theater is $594.50
So, 10.5x +6.5y = 594.50 ......(ii)
After solving equations (i) and (ii), we get the values of x and y as
x = 43 and y = 22
Therefore, the theater sells 43 adult tickets and 22 child tickets.

Givin the figure below,find the values of x and z
Answer:
First, find x.
(12x + 20) + (6x + 70) = 180 (sum of angles on straight line = 180°)
18x + 90 = 180
18x = 90
x = 5
Next, find z.
z = 12x + 20 (vertically opposite angles)
Substitute x = 5 into equation.
z = 12(5) + 20

For the polynomial function f(x)=x^3 - 2x^2 - 5x + 6, we have f(0)=6, f(2) = -4, f(-2) = 0, f(3) = 0 , f(-1) = 8 , f(1) =0. Rewrite f(x) as a product of linear factors.
The given polynomial function f(x)=x^3 - 2x^2 - 5x + 6 as a product of linear factors as (x+2).(x-3).(x-1)
In the above question, a polynomial function is given
f(x)=x^3 - 2x^2 - 5x + 6
However, we know that, zero of a polynomial means all the x-values that bring a polynomial, p(x), to zero are referred to as its zeros, which means putting any value of x in the function we should get value of f(x) as zero
And, in the question, it is given as
f(0)=6, f(2) = -4, f(-2) = 0, f(3) = 0 , f(-1) = 8 , f(1) =0
We can clearly see that, f(-2) = 0, f(3) = 0, f(1) =0
=> (x+2), (x-3), (x-1) are the linear factors of the given polynomial
Hence, we can write the given polynomial function f(x)=x^3 - 2x^2 - 5x + 6 as a product of linear factors as (x+2).(x-3).(x-1)

an article is $68000 and sold at a profit of 14%. Find the selling price
Answer:
The selling price is: [tex]\$77,520[/tex]
Step-by-step explanation:
Step 1: Identify the profit made
A profit of 14% is made on the article.
This means that the article was sold at a price that had 14% of its original price added to it.
The 14% of the original price is:
[tex]14\% \times 68000\\=\frac{14}{100}\times 68000\\\\\text{Calculate the value}\\\frac{14}{100}\times 68000\\=9520[/tex]
So, a profit of $9520 was made
Step 2: Calculate the selling price
The selling price will be the sum of the original price and the profit.
The selling price is:
[tex]68000+9520\\=77520[/tex]

The people of the Plymouth Colony fail to achieve the ideals of the Mayflower Compact as A. They did not come together to create a government.
What was Mayflower Compact?
The Mayflower Compact was the Plymouth colony's first government instrument. The Pilgrim Fathers, the emigrants who crossed the Atlantic on the Mayflower in search of religious freedom, wrote the manifesto. On November 11, 1620, it was signed on the sands of what is now Provincetown, near Cape Cod. The pilgrims knew they were in a land unfamiliar to the London Company when the Mayflower docked in Plymouth.
The strangers claimed that the Virginia Company contract was null and void. They believed that because the Mayflower landed outside of Virginia Company territory, they were no longer bound by the charter of the company. Because there was no official government over them, the stubborn strangers refused to acknowledge any regulations.
Many of the pilgrims were already weak from disease and a lack of food when they arrived in Plymouth. The journey had been lengthy, and they were running low on supplies. During the winter, the colony lost about half of its population owing to disease and famine.

The solutions to the rational equation x / (x + 4) = 20 / (x² + 3 · x - 4) + 2 / (x - 1) are 7 and - 4, respectively.
How to simplify a rational equationIn this problem we find a rational equation that must be solved for x by means of algebraic properties. The complete procedure is shown below:
Step 1 - We have the following expression:
x / (x + 4) = 20 / (x² + 3 · x - 4) + 2 / (x - 1)
Step 2 - Factor x² + 3 · x - 4:
x / (x + 4) = 20 / [(x + 4) · (x - 1)] + 2 / (x - 1)
Step 3 - By existence of multiplicative inverse, modulative, associative and commutative properties:
[x · (x - 1)] / [(x + 4) · (x - 1)] = 20 / [(x + 4) · (x - 1)] + [2 · (x + 4)] / [(x + 4) · (x - 1)]
Step 4 - By compatibility with multiplication, existence of multiplicative inverse, modulative, associative and commutative properties:
x · (x - 1) = 20 + 2 · (x + 4)
Step 5 - By distributive property:
x² - x = 20 + 2 · x + 8
Step 6 - By compatibility with addition, distributive, modulative and associative properties:
x² - 3 · x - 28 = 0
Step 7 - Factor x² - 3 · x - 28:
(x - 7) · (x + 4) = 0
Step 8 - By understanding the factors found in the previous, we get the folowing result:
x = 7 or x = - 4 Result

How to determine the line equation?The table represents the given parameter
On the table, we have the following points
Point, (x, y) = (0, -1) and (2, -6)
So, we start by calculating the slope of the line using the following slope equation
Slope = (y₂ - y₁)/(x₂ - x₁)
Where x and y are defined above
So, we have
Slope = (-6 + 1)/(2 - 0)
Evaluate
Slope = -2.5
The equation of the line is then calculated as
y = m(x - x₁) +y₁
Where
Slope, m = -2.5
(x₁, y₁) = (0, -1)
So, we have
y = -2.5(x + 0) - 1

The approximate probability that between 70 and 90 is 0.728.
Using normal distribution,
Mean = xbar = np = 400 × 0.2 = 80
Standard deviation = √[np(1-p)] = √(80 × 0.8) = 8
To ensure that the distribution is normal,
np ≥ 10
80 ≥ 10
And,
np(1-p) ≥ 10
80(0.8) = 320 ≥ 10
Hence, we use the z-tables for this
a) Convert 75 and 100 into standardized scores.
A value's standardized score is equal to the value minus the mean divided by the standard deviation.
z = (x - xbar) ÷ σ
For 75
z = (75 - 80) ÷ 8 = - 0.625
For 100
z = (100 - 80) ÷ 8 = 2.5
To calculate the approximate likelihood that between 75 and 100 (inclusive) mufflers will be replaced under warranty.
P(75 ≤ x ≤ 100) = P(-0.625 ≤ z ≤ 2.5)
For these probabilities, use data from the normal probability table.
P(75 ≤ x ≤ 100)
= P(-0.625 ≤ z ≤ 2.5)

[tex]\textsf{Midpoint}=\left(\dfrac{x_2+x_1}{2},\dfrac{y_2+y_1}{2}\right)\\\\ \textsf{where $(x_1,y_1)$ and $(x_2,y_2)$ are the endpoints.}[/tex]
Given information:
Midpoint = (-6, -2)E = (10, -8)Define the endpoints of the line segment EF:
Let (x₁, y₁) = endpoint E = (10, -8)Let (x₂, y₂) = endpoint FSubstitute the given information into the formula:
[tex]\implies (x_M,y_M)=\left(\dfrac{x_F+x_E}{2},\dfrac{y_F+y_E}{2}\right)[/tex]
[tex]\implies (-6,-2)=\left(\dfrac{x_F+10}{2},\dfrac{y_F-8}{2}\right)[/tex]
Find the x-coordinate of M:
[tex]\implies \dfrac{x_F+10}{2}=-6[/tex]
[tex]\implies x_F+10=-12[/tex]
[tex]\implies x_F=-22[/tex]
Find the y-coordinate of M:
[tex]\implies \dfrac{y_F-8}{2}=-2[/tex]
[tex]\implies y_F-8=-4[/tex]
[tex]\implies y_F=4[/tex]
Therefore, the coordinates of endpoint F are (-22, 4).
The perimeter of a rectangle is 82 cm the length is 1 cm more than three times the width find the length and the width of the rectangle
The length will then be L = 18(41/19) = 738/19 cm.
As a check, the area should be A = LW = (738/19)(41/19) = 30258 cm2
sorry if this isn't much help but i had a similar problem once and i used the same steps for your question
