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

1. A store had 235 MP3 players in the month of January. Every month, 30% of the MP3 players were sold and 50 new MP3 players were stocked in the store.
Which recursive function best represents the number of MP3 players in the store f(n) after n months?
f(n) = 0.7 x f(n − 1) + 50, f(0) = 235, n > 0
f(n) = 237 − 0.7 x f(n − 1) + 50, f(0) = 235, n > 0
f(n) = 0.3 x f(n − 1) + 50, f(0) = 235, n > 0
f(n) = 237 + 0.7 x f(n − 1) + 50, f(0) = 235, n > 0

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].

Two trucks leave a warehouse at the same time. one travels due north at an average speed of 48 miles per hour, and the other travels due south at an average speed of 64 miles per hour. after how many hours will the two trucks be 728 miles apart?
When two objects are moving in opposite directions, their relative speed is the sum of their speeds. In this scenario, the trucks will be 728 miles apart after 6.5 hours of travel.
Explanation:The problem here is essentially an application of the concept of relative speed. The two trucks are traveling in opposite directions, so you add their speeds together to get the relative speed at which they are moving apart. That results in a combined speed of 48 mph (north) + 64 mph (south) = 112 mph. Now, to find out when they will be 728 miles apart, you divide the total distance by the combined speed:
728 miles ÷ 112 mph = 6.5 hours.
So, both trucks will be 728 miles apart after 6.5 hours.

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].
A sea turtle swims at a speed of 27 kilometers per hour. A girl swims 14 decimeters per second.
1 m = 10 dm
1000 m = 1 km
How much faster does the sea turtle swim than the girl in meters per minute?
Enter your answer in the box.
____m/min
~~~~~~~~~~The answer is 366 m/min~~~~~~~~~~~~~~~~~~ First, convert the turtles speed to meters per minute. 27 km/h * 1000 m/km = 27000 m/h / 60 min/h = 450 m/min Now convert the girls speed to meters per minute. 14 dm/s / 10 dm/m * 60 s/min = 84 m/min Now subtract the girl's speed from the turtle's speed. 450 m/min = 84 m/min = 366 m/min

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.
