Answer:
The correct option is C.
Step-by-step explanation:
Consider the provide information.
Now consider the provided options
Option A) If there is a coordinate plane with two parallel lines.
if the plane has two parallel line then, It has no solution because you can get the solution if lines intersect at a point. Thus, it is not the required option.
Option B) and D) If there are two intersecting lines then you can get only one solution. Thus, it is not the required option.
Option C) If there are two coinciding lines then you can find infinite intersecting points. Thus, it is the required option.
Therefore, the correct option is C.

A car travels 0.75 every minute. Explain how could you use proportional reasoning to find how far the car travels in one hour
Answer:
Sample Response: Identify the unit rate as 0.75 miles per 1 minute. Since there are 60 minutes in an hour, multiply 0.75 time 60 to find how far the car travels in one hour.
Step-by-step explanation:
Write an equation for a rational function with: vertical asymptotes at x = -4 and x = 4 x-intercepts at x = -6 and x = 5 horizontal asymptote at y = 8
A rational function with the required characteristics is f(x) = 8(x + 6)(x - 5) / (x + 4)(x - 4), considering vertical asymptotes, x-intercepts, and a horizontal asymptote.
Explanation:To write an equation for a rational function with given characteristics, we need to incorporate the vertical asymptotes, x-intercepts, and horizontal asymptote into our function.
Firstly, vertical asymptotes at x = -4 and x = 4 suggest that the denominator of our function will be in the form (x + 4)(x - 4), as setting x to -4 or 4 will make the denominator zero, which creates the asymptotes.
Secondly, x-intercepts at x = -6 and x = 5 indicate that the numerator will have factors that become zero at these x-values. Hence, the numerator should be(x + 6)(x - 5).
Finally, for the function to have a horizontal asymptote at y = 8, the degree of the numerator and denominator must be the same, and the leading coefficients of the numerator and denominator must have a ratio that equals 8. To achieve the horizontal asymptote, we multiply the numerator by 8, thus the leading coefficients of the numerator and denominator are in the ratio 8:1.
Combining all these elements gives us our rational function: f(x) = 8(x + 6)(x - 5) / (x + 4)(x - 4)

Find the least common multiple of x 3 - x 2 + x - 1 and x 2 - 1. write the answer in factored form.
a. (x + 1) 2(x - 1)
b. (x + 1)(x - 1)(x 2 + 1)
c. (x 3 - x 2 + x - 1)(x 2 - 1)
d. (x + 1)(x - 1)(x 2 - 1)
The correct answer is d. [tex](x + 1)(x - 1)(x^2 - 1)[/tex].
To find the least common multiple (LCM) of the two polynomials[tex]\(x^3 - x^2 + x - 1\) and \(x^2 - 1\)[/tex], we need to factor each polynomial and then find the LCM of the factors.
First, let's factor [tex]\(x^3 - x^2 + x - 1\)[/tex]:
[tex]\(x^3 - x^2 + x - 1 = x^2(x - 1) + (x - 1) = (x^2 + 1)(x - 1)\)[/tex].
Now, let's factor [tex]\(x^2 - 1\)[/tex]:
[tex]\(x^2 - 1 = (x + 1)(x - 1)\)[/tex].
The LCM of two polynomials is the product of the highest powers of all the factors that appear in either polynomial. Here, we have the factors [tex]\(x - 1\), \(x + 1\), and \(x^2 + 1\)[/tex] from the first polynomial, and the factors [tex]\(x - 1\) and \(x + 1\)[/tex] from the second polynomial.
Since [tex]\(x^2 + 1\)[/tex] is already the highest power of [tex]\(x^2 + 1\) , \(x - 1\) and \(x + 1\)[/tex] are the highest powers of [tex]\(x - 1\) and \(x + 1\)[/tex] respectively, the LCM is simply the product of all these factors:
[tex]\((x + 1)(x - 1)(x^2 + 1)\)[/tex].
However, we notice that [tex]\(x^2 - 1\)[/tex] is actually equal to [tex]\((x + 1)(x - 1)\)[/tex], and since [tex]\(x^2 + 1\)[/tex] is not a factor of [tex]\(x^2 - 1\)[/tex], we do not include it in the LCM. Therefore, the LCM is just [tex]\((x + 1)(x - 1)\)[/tex].
But we must also consider the polynomial [tex]\(x^3 - x^2 + x - 1\)[/tex], which can be rewritten as [tex]\((x^2 + 1)(x - 1)\)[/tex]. Since [tex]\(x^2 + 1\)[/tex] is not a factor of [tex]\(x^2 - 1\)[/tex], it must be included in the LCM to account for the additional factor in the first polynomial.
Thus, the LCM of [tex]\(x^3 - x^2 + x - 1\) and \(x^2 - 1\)[/tex] is [tex]\((x + 1)(x - 1)(x^2 - 1)\)[/tex], which corresponds to option d. This is because we take the highest powers of the common factors [tex]\((x + 1)\) and \((x - 1)\)[/tex], and include the additional factor from the first polynomial, which is [tex]\(x^2 - 1\)[/tex] since [tex]\(x^2 + 1\)[/tex] is not a factor of[tex](x^2 - 1\))[/tex].
Therefore, the final answer is [tex]\(\boxed{(x + 1)(x - 1)(x^2 - 1)}\)[/tex].

Given △ABC≅△JKL , m∠B=55° , and m∠L=25° , what is the measure of ∠J ? Enter your answer in the box.
Answer:
m∠J = 100° is the answer.
Step-by-step explanation:
Given : ΔABC ≅ ΔJKL,
m∠B = 55°
m∠L = 25°
To find : ∠J
Since in both the triangles ABC and JKL
m∠A ≅ m∠J
m∠B ≅ m∠K = 55°
m∠C ≅ m∠L = 25°
Since measure of ∠K and ∠L are known then we can calculate the third angle j
m∠J + m∠K + m∠L = 180°
55° + 25° + m∠J = 180°
80° + m∠J = 180°
m∠J = 180 - 80
= 100°
Therefore, m∠J = 100° is the answer.
H=62.4Ns/33,000 solve for N
please help
Answer:
[tex]N=\frac{33,000H}{62.4s}[/tex]
Step-by-step explanation:
We have been given an equation [tex]H=\frac{62.4Ns}{33,000}[/tex]. We are asked to solve our given equation for N.
Multiply both sides by 33,000:
[tex]H*33,000=\frac{62.4Ns}{33,000}*33,000[/tex]
[tex]33,000H=62.4Ns[/tex]
Switch sides:
[tex]62.4Ns=33,000H[/tex]
Divide both sides by [tex]62.4s[/tex]:
[tex]\frac{62.4Ns}{62.4s}=\frac{33,000H}{62.4s}[/tex]
[tex]N=\frac{33,000H}{62.4s}[/tex]
Therefore, the value of N is [tex]\frac{33,000H}{62.4s}[/tex].

P(x) = x2 – 1 and q(x)=5(x-1), which expression is equivalent to (p – q)(x)?
Answer: The required expression is [tex]x^2-5x+4.[/tex]
Step-by-step explanation: We are given that
[tex]p(x)=x^2-1,\\\\q(x)=5(x-1).[/tex]
We are to find the expression that is equivalent to (p-q)(x).
We know that for any two functions f(x) and g(x), we have
[tex](f-g)(x)=f(x)-g(x).[/tex]
Therefore we get
[tex](p-q)(x)\\\\=p(x)-q(x)\\\\=(x^2-1)-(5(x-1))\\\\=x^2-1-5x+5\\\\=x^2-5x+4.[/tex]
Thus, the required expression is [tex]x^2-5x+4.[/tex]

As Mercury revolves around the sun, it travels at a rate of approximately 30 miles per second. Convert this rate to miles per minute. At this rate, how many miles will Mercury travel in 4 minutes?
The number of miles that Mercury travels in 4 minutes will be 7,200 miles.
What is the rate?The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.
Unit modification is the process of converting the measurement of a given amount between various units, often by multiplicative constants that alter the value of the calculated quantity without altering its impacts.
As Mercury revolves around the sun, it travels at a rate of approximately 30 miles per second.
Convert the rate into miles per minute. Then we have
Rate = 30 x 60
Rate = 1,800 miles per minute
At this rate, the number of miles that Mercury travels in 4 minutes will be given as,
D = 1,800 x 4
D = 7,200 miles
The number of miles that Mercury travels in 4 minutes will be 7,200 miles.

Is y=4x-1 and 12x=3y+7 parallel, perpendicular, or neither
Answer:
Neither is the answer.
Step-by-step explanation:
If a line y = m₁x + c₁ and y = m₂x + c₂ are perpendicular to each other then m₁ × m₂ = -1
If both the lines are parallel to each other then m₁ = m₂
Now two lines have been given as
y = 4x - 1 ----------(1)
12x = 3y + 7
3y = -12x + 7
y = -4x + [tex]\frac{7}{3}[/tex]------(2)
Now from equation (1) and equation (2),
m₁ = 4 and m₂ = -4
Since m₁ ≠ m₂
Therefore, these lines are not parallel
m₁ × m₂ = 4 × (-4) = -16
Therefore, both the lines are neither parallel nor perpendicular.

a regular polygon must have ___ sides if each interior angle measure is four times the measure of each exterior angle
The sum of the interior angles of the polygon is 1440° and the number of sides of the polygon is 10 sides
What is the sum of the interior angles of a polygon?The sum of the interior angles of a polygon is given by the formula
Sum of Interior angles of a polygon with n sides is
nθ = 180 ( n - 2 )
where n is the number of sides
θ = angle in degrees
Given data ,
Let the sum of the interior angles of the polygon be S
Now , the number of sides = n
The sum of the exterior angles of a polygon = 360°
And , each interior angle measure is four times the measure of each exterior angle
Substituting the values in the equation , we get
180 ( n - 2 ) = 4 ( 360 )
On simplifying the equation , we get
180n - 360 = 1440
Adding 360 on both sides of the equation , we get
180n = 1800
Divide by 180 on both sides of the equation , we get
n = 10 sides
Hence , the number of sides of the polygon is 10 and it is a decagon
