What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
We know that the product of slopes of perpendicular lines is -1.
mM=-1
m is slope of one line and M is the slope of perpendicular line.
M=-1/m
y=1/3x+4
The perpendicular line is y=-3x-4
y=2/5x-7
The perpendicular line is y=-5/2x+7
y=-5/2x+8
The perpendicular line is y=2/5x+6
y=-2x+6
The perpendicular line is y=1/2x+3
y=7/5x-9
The perpendicular line is y=-5/7x-11.
Hence, the lines with corresponding perpendicular lines are
y=1/3x+4---> y=-3x-4
y=2/5x-7-----> y=-5/2x+7
y=-5/2x+8----->y=2/5x+6

A rectangle with a perimeter of 40 inches has a width that is 3 times the length. What is the length And the width
Answers
The Length is 5 inches and the Breadth is 15 inches
What is Perimeter?
A perimeter is a closed route that covers, surrounds, or outlines a two-dimensional form or length. The circumference of a circle or an ellipse is its perimeter. There are various practical applications for calculating the perimeter.
Solution:
Perimeter of Rectangle = 2*(Length + Breadth)
According to the question
Breadth = 3*Length
Perimeter = 40
40 = 2*(Length + 3*Length)
20 = 4*Length

You have one type of chocolate that sells for $2.10/lb and another type of chocolate that sells for $9.90/lb. You would like to have 62.4 lbs of a chocolate mixture that sells for $2.40/lb. How much of each chocolate will you need to obtain the desired mixture?
You will need __ lbs of the cheaper chocolate and __ lbs of the expensive chocolate.
Answers
Answer:
This is a problem of weighted averages and can be solved with a system of equations.
Let's define:
- `x` as the amount (in lbs) of the cheaper chocolate,
- `y` as the amount (in lbs) of the expensive chocolate.
We can set up the following equations:
1. `x + y = 62.4` (the total amount of chocolate we want)
2. `$2.10x + $9.90y = $2.40 * 62.4` (the total cost of the chocolate mixture)
The second equation represents the total value of the chocolate, while the first represents the total weight.
We can solve this system of equations using substitution or elimination. In this case, it may be simpler to use elimination.
Let's first transform the second equation to get rid of the dollar signs:
2.10x + 9.90y = 2.40 * 62.4
2.10x + 9.90y = 149.76
Let's now multiply the first equation by 2.10 (the price per lb of the cheaper chocolate):
2.10x + 2.10y = 2.10 * 62.4
2.10x + 2.10y = 131.04
Subtracting the second equation (multiplied) from the original second equation, we get:
9.90y - 2.10y = 149.76 - 131.04
7.80y = 18.72
Solving for y, we get:
y = 18.72 / 7.80 = 2.4 lbs
Substituting y = 2.4 into the first equation:
x + 2.4 = 62.4
x = 62.4 - 2.4 = 60 lbs
So, you will need 60 lbs of the cheaper chocolate and 2.4 lbs of the expensive chocolate to obtain the desired mixture.

What is a right triangle?
A right triangle, also known as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or formerly rectangle triangle, is a triangle with one right angle, or two perpendicular sides. The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.
Given the acute angle of a right triangle is 6 more than 3 times the measure of the other small angle.
Assume that the measurement of smaller angle is x.
Then the mathematical expression of 6 more than 3 times of x is 6 + 3x.
The measure of third angle is 90° since it a right triangle.
The sum of all interior angles of a right triangle is 180°.
The equation is
x + (6 + 3x) + 90 =180
x + 6 + 3x + 90 =180
Combine like terms:
(x + 3x) + (6 + 90) = 180
4x + 96 = 180
Subtract 96 from both sides:
4x = 180 - 96
4x = 84
Divide both sides by 4
x = 21
Putting x = 21 in the expression (6 + 3x) :
6 + 3x = 6 + 63 = 69.

what is 2 4/5+ 4/6 equivalent to?
Answers
Answer:
To find the equivalent of 2 4/5 + 4/6, we first need to convert the mixed numbers to improper fractions. To do this, we multiply the whole number part of the mixed number by the denominator of the fraction part, and add the result to the numerator of the fraction part. So 2 4/5 becomes 2 * 5 + 4 = 14/5. Similarly, 4/6 becomes 4 * 1 + 6 = 10/6.
Next, we need to find a common denominator for the two fractions so that we can add them. A common denominator for 14/5 and 10/6 is 30, so we convert both fractions to have a denominator of 30. To convert 14/5 to have a denominator of 30, we multiply the numerator and denominator by 6, which gives us 14 * 6 / 5 * 6 = 84/30. Similarly, we multiply the numerator and denominator of 10/6 by 5 to get 10 * 5 / 6 * 5 = 50/30.
Now that both fractions have a denominator of 30, we can add them to get the equivalent of 2 4/5 + 4/6. This gives us 84/30 + 50/30 = 134/30. Finally, we simplify the fraction to get the final answer, which is 134/30 = 4 8/30 = 4 4/15. So, the equivalent of 2 4/5 + 4/6 is 4 4/15.

Additional comment
We note that the 3x in the first equation can be substituted by y using the second equation. This gives 5y=240, or y = 48. Then 3x=48, so x=16. This agrees with the graphical solution, as it should.
