The equation of the line that is perpendicular to the given line y = x + 6 and has an x-intercept of 6 is B. y = -x + 6.
A line is plotted on the cartesian plane and is straight, thus named a straight line. A straight line is a two-dimensional geometrical figure.
Given the line:
y = x + 6
Compare the equation with
y = mx + c,
m = 1 and c= 6.
As it is given that the new line is perpendicular to the old one, then
the slope of the new line, m' [tex]= -\frac{1}{m} = -\frac{1}{1} = -1[/tex].
As the x-intercept is 6, c' = 6.
So, the equation of the new line is
y = m'x + c'
y = -x + 6
Therefore, the new line is y = -x + 6.

What do you mean by the term singular?If a singular matrix's determinant is 0, it is a square matrix. Specifically, if and only if det A = 0, a square matrix A is unique. We are aware that the formula A-1 = (adj A) / can be used to get the inverse of a matrix A. Here, the denominator contains det A, which is the determinant of A. We are aware that a fraction with a denominator of 0 is not defined. Since det A = 0, A-1 is not defined. In other words, a single matrix's inverse is not defined. That is to say, there isn't a matrix B such that AB = BA = I.
A singular matrix means that the detA should be 0.

The value of the given quadratic equation are = x = -(6/5) , x = 2
What is quadratic simple?Quadratics are polynomial equations of the second degree, which means they have at least one squared term. It is also known as quadratic equations. The quadratic equation has the general form: ax2 + bx + c = 0.
So, how are quadratic functions significant?Quadratic functions occupy a distinctive place in the school curriculum. They are functions whose values are easily estimated from input values, therefore they are a modest improvement over linear functions and provide a major shift away from attachment to straight lines.
According to the given information:Given (5x + 6)(3x - 6) = 0
Using the zero factor principle: if ab = 0 then a = 0 and b = 0
So,
(5x + 6) = 0 or (3x - 6) = 0
for the (5x + 6):
(5x + 6) = 0 (subtracting both side by 6)
5x + 6 - 6 = 0- 6
so, x = -(6/5)
Same calculation for (3x - 6) = 0 we get x = 2
The value of the given quadratic equation are = x = -(6/5) , x = 2

As per the question statement, Point B [tex](3,1)[/tex] is there on a cartesian plane. Point B is translated 2 units to the right and 1 unit up.
Before solving this question, we need to know about cartesian plane system in which, there are four quadrants which are made using positive and negative axes known as positive X and negative X (same for Y axis).
Now point B[tex](3,1)[/tex] lies in the first quadrant and value "3" describes the location of point on X axis and value "1" describes the location of point on Y axis.
If point B [tex](3,1)[/tex] is translated 2 units to the right and 1 unit up, the locations of X and Y axes will change to value "5" on X axis and value "2" on Y axis.
Hence the coordinates of point B' are [tex](5,2)[/tex]

The area of the playing surface at the Olympics stadium in Beijing is 3/5 of a hectare. What area will it occupy on a plan drawn to a scale of 1:500
The area that occupies on a plan drawn to the given scale is 0.024 m²
Given,
The area of the playing surface at the Olympics stadium in Beijing = 3/5 hectare
The scale factor on a plan drawn = 1:500
We have to find the area that occupies on a plan drawn to the given scale:
Applied to the area we consider k² as the area is the product of two dimensions.
So, k = 1/500
Now the area on plan:
a : k² = actual area
a : (1/500)² = (3/5) × 10000
a : (1/250000) = 3 × 2000
a × 250000 = 6000
a = 6000 / 250000
a = 0.024 m²

The Option A best explains the dual experiments: "In the experimental group, a chosen variable is altered in a known way. In the control group, that chosen variable is not altered so a comparison can be made."
What is experimental design?The process of deciding which variables to use in an experiment to test a particular hypothesis is called experimental design. To properly collect data and evaluate the hypothesis, the experimental design method is used.Now,
A specified variable is changed in the experimental group in a well-known fashion. That selected variable is left unaltered in the control group so that comparisons can be conducted. Control variables are variables that are utilized in an experiment to serve as a baseline against which the data from the experimental variables are gathered and evaluated (which is why the other answers are incorrect). In the experimental group, it is advisable to modify just one variable at a time so that any differences from the control group may be quickly linked to the one variable that was altered.Hence, amongst all the given options, The Option A best explains the dual experiments: "In the experimental group, a chosen variable is altered in a known way.

Convert 3.9 yards to inches.
Answer:
140.4 inches
Step-by-step explanation:
there are 36 inches in a yard
3.9 times 36 is 140.4
Hope It Helps
Sorry If I'm Wrong
3.9 yards is equal to 140.4 inches.
We have,
The concept used to convert 3.9 yards to inches is the conversion factor between yards and inches. The conversion factor states that 1 yard is equal to 36 inches.
By multiplying the given value in yards (3.9 yards) by the conversion factor (36 inches/yard), we can convert the measurement from yards to inches.
This concept of using a conversion factor allows us to convert between different units of measurement.
To convert 3.9 yards to inches, we can use the fact that 1 yard is equal to 36 inches.
So, to convert 3.9 yards to inches, we multiply 3.9 by 36:
3.9 yards * 36 inches/yard = 140.4 inches
Therefore,
3.9 yards is equal to 140.4 inches.

A group of friends wants to go to the amusement park. they have $69.75 to spend on parking and admission. parking is $17.25, and tickets cost $17.50 per person, including tax. write an equation which can be used to determine p, the number of people who can go to the amusement park.
Equation and solution of equation :
17.25 + p(17.50) = 69.75
17.25 + 17.50p = 69.75
17.50x = 69.75 - 17.25
17.50p = 52.50
p = 52.50/17.50
p = 3
So three people can go to the amusement park (assuming that they are all travelling together in the same car).
The equation that represents the number of people who can go to the amusement park will be 17.50p + 17.25 = 69.75.

What is a proportional relationship?A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
In item 18, we have that when x = 2, y = 1, hence the constant is:
k = y/x = 1/2 = 0.5.
Hence the equation is:
y = 0.5x.
In item 22, we have that when x = -5, y = 2, hence the constant is:
k = y/x = -2/5 = -0.4.

One pygmy shrew weighs 3 3/18 ounces, and another weighs 4 4/7 ounces. Estimate the total weight.
O about 8 1/2
O about 7 1/2
O about 9 ounces
O about 7 ounces
==============================================
Reason:
It might help to draw a number line for this.
3/18 is closer to 0 than it is to 1/2 = 9/18, so the mixed number 3 & 3/18 rounds to 3 when rounding to the nearest half.
4/7 is closer to 1/2 = 4/8 than it is to either 0 or 1, so 4 & 4/7 rounds to 4 & 1/2 when rounding to the nearest half.
Adding 3 to 4 & 1/2 gets 7 & 1/2 since we add the whole parts 3+4 = 7, and the fractional part stays as it is.
-----------
Check:
(3 + 3/18) + (4 + 4/7) = 7.738 approximately
7 + 1/2 = 7.5 exactly
The two results aren't too far off. The estimate of 7 & 1/2 is an underestimate.
Answer:
About 7 1/2 ounces
Step-by-step explanation:
Add your whole numbers first, 3 + 4 = 7
Now the fractions:
3/18 = 1/6
Estimate 4/7 + 1/6, the answer is somewhere between 1/2 and 1 whole. Therefore the answer is about 7 1/2
Check:
3/18 × 7/7 = 21/126
4/7 × 18/18 = 72/126
21/126 + 72/126 = 93/126
The actual answer is 7 31/42, so the closest answer is 7 1/2
