The line parallel to y=9x+4 that passes through (2,7)
The equation of the line parallel to y=9x+4 that passes through (2,7) is y = 9x - 11
The equation of a line in point-slope form is expressed as:
y - y0 = m(x-x0)
m is the slope of the line
(x0, y0) is any point on the line
Given the equation y = 9x + 4, the slope of the line is expressed as:
mx = 9x
m = 9
We will use the same slope since the lines are parallel
Substitute the slope and the given point into the formula;
y - 7 = 9 (x -2)
y - 7 = 9x - 18
y = 9x -18 +7
y = 9x - 11
Hence the equation of the line parallel to y=9x+4 that passes through (2,7) is y = 9x - 11

Answer: c
Step-by-step explanation: a p e x
The area of the given Octagon is 1,086 units²
What is an Octagon?A polygon of eight angles and eight sides is called an Octagon.
Given is a figure of an Octagon, having radius = 18.1 units and side length = 15 units.
The regular octagon is divided into 8 triangles
Therefore, the area of a regular octagon = the sum of the area of 8 triangles
The area of a triangle = 1/2(base)(height)
Here, base = 15 units and length = 18.1 units
Therefore, the area of a regular octagon = 1/2×15×18.1×8 = 1,086
Hence, The area of the given Octagon is 1,086 units²

what is the domain of the following parabola
Answer:
C. All real numbers.
Step-by-step explanation:
We have been given an image of a parabola. We are asked to find the domain of given parabola.
We know that domain of a function is all real values of x for which function has a defined value.
We know that domain of a quadratic function is all real numbers, therefore, option C is the correct choice.
Answer: R
Step-by-step explanation: The domain of a function is the set of all x-values of the function.
The x-values on a coordinate system are the left-and-right values and
we can see that the parabola is expanding infinitely to the left and
to the right so the domain of the function is all real numbers.
Although there is an all real numbers option, you can also represent

Which of the following equations represents a line that is perpendicular to the line that passes through the points below?
(-8, -10) (-6, -2)
Thank you!
By calculating the slope of the line passing through the given points to be 4, the slope of any line perpendicular to this would have the opposite reciprocal, -1/4. Without a specified point for the line to pass through, (0,0) is used and the equation of the perpendicular line is y = -1/4x.
Explanation:The first step to finding a line perpendicular to another is understanding the concept behind the slope of a line. The slope of a line is determined by comparing the vertical change (rise) to the horizontal change (run) between two points on a line.
For the points (-8, -10) and (-6, -2), the slope would be calculated as follows: (change in y)/(change in x), which in this case would be (-2 - (-10))/(-6 - (-8)). Simplifying that expression gives us a slope of 4.
The opposite reciprocal of 4 is -1/4 (we flipped the fraction and changed the sign). This is the slope of all lines perpendicular to the original line.
Lastly, for the equation of a line, we need a point for the line to pass through, since the question didn't specify a point, we can use (0,0), so the equation of our perpendicular line is y = -1/4x.

The sample mean is calculated by adding up all the values in a sample and then dividing this total by the number of values in the sample.
Explanation:When you calculate the sample mean, you divide the sum of the values in the sample by the number of values in that sample. For instance, if your sample contains the values 2, 4, and 6, you would add all these values together to get 12. Then, you would divide this total by 3, because there are three values in your sample.

Zeke ran 4 miles in 45 minutes. if he keeps up the same pace, how long will it take him to run 10 miles?
Final answer:
Zeke's pace is approximately 5.33 miles per hour. To run 10 miles at this pace, it will take him about 113 minutes.
Explanation:
To solve how long it will take Zeke to run 10 miles at the same pace, we need to establish his running speed. We know that Zeke ran 4 miles in 45 minutes, which we can convert to hours for simplicity. Since there are 60 minutes in an hour, this is ⅔ of an hour. So, Zeke's pace is 4 miles per ⅔ hour, or 4 miles per 0.75 hours, which is ≈ 5.33 miles per hour.
Now, we use this pace to determine how long it will take him to run 10 miles. If Zeke runs at a pace of 5.33 miles per hour, then we can calculate the time for 10 miles by dividing the distance by the speed:
Time = Distance ÷ Speed
Time = 10 miles ÷ 5.33 miles/hour
Time ≈ 1.88 hours
Since we want the time in minutes, we multiply by 60 minutes per hour:
1.88 hours × 60 minutes/hour ≈ 112.8 minutes
So, it would take Zeke approximately 113 minutes to run 10 miles at the same pace.

Mr. Malone used 40 pounds of insecticide to cover 1,760 square feet of lawn and 60 pounds to cover an additional 2,640 square feet. how many pounds of insecticide would Mr. Malone need to cover his whole lawn of 4,480 square feet?
Answer:
101.8182 pounds.
Step-by-step explanation:
He used 40 pounds of insecticide to cover 1760 square feet of lawn and 60 pounds to cover an additional 2640 square feet. So,
1760 + 2640 = 4400 square feet of lawn with 40+60 = 100 pounds of insecticide. Then, his whole lawn is 4480 square feet andn he already covered 4400, so he need to cover 4480 - 4400 = 80 square feet more.
Now, one of the data given we can do a proportion:
40 pounds to 1760 square feet = [tex]\frac{40pounds}{1760ft^2}[/tex]
x pounds to 80 square feet = [tex]\frac{xpounds}{80ft^2}[/tex]
[tex]\frac{40pounds}{1760ft^2}=\frac{xpounds}{80ft^2}[/tex]
[tex]xpounds*1760ft^2 = 80ft^2*40pounds[/tex]
[tex]xpounds = \frac{80ft^2*40pounds}{1760ft^2}[/tex]
[tex]xpounds = \frac{3200pounds}{1760}[/tex]
[tex]x = 1.8182 pounds.[/tex]
Then, to cover his whole lawn of 4480 square feet he needs 100+1.8182 = 101.8182 pounds of insecticide.

2x+4y=−12
(?,?)
Please Help!
Answer:
The solution of the equation −4x−2y=−12 , 2x+4y=−12 are (6 , -6) .
Step-by-step explanation:
As given the equations are
−4x−2y = −12
Simplify the equation
-2(2x + y) = -12
2x + y = 6
Another equation
2x+4y=−12
2(x+2y) = −12
x + 2y = -6
Two equation becomes
2x + y = 6
x + 2y = -6
Multiply x + 2y = -6 by 2 and subtracted from 2x + y = 6 .
2x - 2x + y - 4y = 6 + 12
-3y = 18
[tex]y = \frac{-18}{3}[/tex]
y = -6
Putting the value of y in the equation
2x + -6 = 6
2x = 12
[tex]x = \frac{12}{2}[/tex]
x = 6
Therefore the solution of the equation −4x−2y=−12 , 2x+4y=−12 are (6 , -6) .

What is the area of a parallelogram whose vertices are A(−12, 2) , B(6, 2) , C(−2, −3) , and D(−20, −3) ?
Enter your answer in the box.
To solve this, we simply have to get the length and the width. Based from the graph, we can see that the length is connected by 2 points (-12, 2) and (6, 2) or (-20, -3) and (-2, -3). The height between the two lengths is 5 which can be counted manually.
We use the distance formula to calculate the length from either pair of points.
length^2 = [(-12 – 6)^2 + (2 – 2)^2]
length = 18
Therefore the area is:
Area = length * height
Area = 18 * 5
Area = 90
Which equation in point-slope form contains the points (8, 10) and (–4, 2)?
The equation in point-slope form containing the points (8, 10) and (-4, 2) is y - 10 = (2/3)(x - 8).
Explanation:The point-slope form of a linear equation is given by where (x1, y1) represents the given point and m represents the slope. To find the equation in point-slope form containing the points (8, 10) and (-4, 2), we need to calculate the slope first. The slope m can be calculated using the formula m = (y2 - y1) / (x2 - x1).
Using the given points (8, 10) and (-4, 2), we can substitute the values into the formula to find the slope:
Now that we have the slope, we can use one of the given points to write the equation in point-slope form. Let's use the point (8, 10):
