Answer: m=1/2; b=-5
Step-by-step explanation:
We can use the given points to find slope, then use the y=mx+b equation to find the y-intercept. The formula for slope is [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex].
[tex]m=\frac{-8-(-2)}{-6-6}=\frac{-6}{-12} =\frac{1}{2}[/tex]
Now that we know m=1/2, we can use that in y=mx+b to find the y-intercept. We can use any given point to plug into x and y.
y=1/2x+b [plug in x and y]
-2=1/2(6)+b [multiply]
-2=3+b [subtract both sides by 3]
b=-5
Now, we know that b=-5.

Geometry ∠1 and ∠2 are vertical angles. If m∠1 = 17x + 1 and m∠2 = 20x – 14, find m∠2.
Answer:
m∠2= 86
Step-by-step explanation:
since they are vertical angles, that means they are both equal to eachother.
so lets set them equal!
17x+1=20x-14
17x+15=20x
15=3x
x=5
now input x into m∠2
m∠2 = 20(5) – 14 = 86
р – (4р – 8) = 7(p — 2)
Answer:
Step-by-step explanation:
p - 4p + 8 = 7p - 14
-3p + 8 = 7p - 14
-10p + 8 = -14
-10p = -22
p = 22/10
p = 2.2

We just got it right on my son's quiz but we figured it out by:
Multiplying both the numerator and denominator by 2.The table shows the hourly wages (in dollars) of employees after they have worked at a company for 2 years. Use the linear regression feature on a
graphing calculator to find an equation of the line of best fit for the data. Round each value in your equation to the nearest hundredth. Then use your
equation to estimate the hourly wage of an employee who has worked at the company for 15 years.

The approximate hourly wage of a person who has worked at the company for 15 years is $
per hour
Answer:
y= 0.5x + 8.2

Step-by-step explanation:
(Is it weird that I had the same exact question? Maybe not. But I also found another person with the same question as me. It was a different question though. This is probably too late. But I'm just gonna try to answer it for anyone who needs it.
"Linear regression" is just a fancy word for scatter plots. Scatter plots take place in graphs. The dots or plots are scattered and the way they are scattered means something. If it's going down, it's negative, up it's positive, and if it's scattered, it has no corrolation.
Also, you should have learned this in 9th grade. So, check your notes.
If you don't have it, WRITE IT!!!
To find it in your calculator:
1. Go to "Lists and Spreadsheets"
2. Rename the first column "x" and the second on "y"
3. Write all of your numbers in the right column
1, 5, 3, 7 under the "x"8.67, 10.50, 9.58, 11.41 under the "y"4. Move your cursor to an empty cell
4. Click: "MENU" #4 #1 #3
5. Rename the correct rows "x" and "y" and press enter
6. Now you can find "m" and "b"
7. Then move your cursor to an empty cell and click "doc" "insert" #7
8. Find the x-axis and find "x"
9. Find the y-axis and find "y"
10. Now press "MENU" #4 #6 #1
And you found your y=mx+b: y=0.5x+8.2
Now, how much money per hour.
So you've found your m and b but now you have to:
1. Replace y with 15 and solve it
15=0.5x+8.2-8.2 -8.26.8=0.5xDivide 0.5 on both sides6.8/0.5=13.613.6=x$13.6 per hour

How do I solve it ? I don’t understand
Answer:
1) 3 Points Include: E, B and F. To explain in Detail. Point E, which is (-1,1) Point B, which is (0,-2) and Point F, which is (2,3) The Directions tell you to name 3 Points on the image. The points I just explained are all on the graph, so they are all points in the Image.
Two Lines are: Lines CD and Lines AB. These are both lines on the images. The points A and B are connected with a line, so they are a line on the graph. The Points C and D are also connected by a line, therefore, both lines CD and AB are lines on the image.
A Line Segment: A line segment is a line connected with two end points, You can say a line is a segment when both ends of the line have a dot, also known as a point. One line segment in this image is Line EB, both the points are connected by a line, and both sides of the line have a point.
The Plane: The plane is the entire surface that everything is on. The plane has all the lines, segments, and points. All planes extend infinitely far. We can see, the plane is "O". The letter O is located towards the middle of the graph, Therefore, the Plane is "O"
2)One Point: On the Plane, one point is point S. Q and R are also points, but the question only asks for one point.
The Line: There is only one line on the plane, this line is line QR. Both points Q and R are connected by a line.
The Plane: The Plane is "T" in the bottom left of the image, in the corner of the plane (the plane is the blue area) you can see the letter T. "T" is the plane.
Does the line go through the Plane? Yes. The line does go through the plane. Here's why: On the line QR, both sides of the line have arrows. If a line has arrows that means the line goes on forever in the direction the arrow is pointing. If a line has two dots, its a segment, which means the lines end at the points, they do not go on forever. In this case, the line goes on forever and it goes through the blue area, which is the plane.

Simplify your answer and write it as a proper fraction, mixed number, or integer.
Submit
Answer:
EF = 8
Step-by-step explanation:
The following data were obtained from the question:
EF = 2x
FG = 8
EG = 4x
EF =?
To obtain the value of EF, we shall first, obtain the value of x. This can be obtained as follow:
EG = EF + FG
EF = 2x
FG = 8
EG = 4x
4x = 2x + 8
Collect like terms
4x – 2x = 8
2x = 8
Divide both side by 2
x = 8/2
x = 4
Therefore, the value of x is 4.
Finally, we shall determine the the value of EF as follow:
EF = 2x
x = 4
EF = 2x
EF = 2(4)
EF = 8
**** Check ****
EG = EF + FG
EF = 2x
EG = 4x
FG = 8
4x = 2x + 8
x = 4
4(4) = 2(4) + 8
16 = 8 + 8
16 = 16

Answer:
= 192
Step-by-step explanation:
a²b²c² = 2²3²4² = (2×2)(3×2)(4×2) = (4)(6)(8) = (24)(8) = (192) = | 192 | = 192
Answer: IT IS 576
Explanation:
So, if a=2 then, 2 to the second power (squared) is 4. b(3) to the second power(squared) is 9. c (4)to the second power(squared) is 16.
One way you can remember it is if you do 1 times 1, 2 times 2, 3 times 3, and so on.
So between the answers of:

A ballroom has a square dance floor. The area of the floor is 400 square feet.
If the length of each side of the square increased by one foot, would its area be a rational number?
Choose all that apply.
Answers:
A. - The area of the floor would be a rational number.
B. - The area of the floor would be an irrational number.
C. - Each side length would be a perfect square.
D. - The area of the floor would be a perfect square.
E. - The area of the floor would be a nonterminating, nonrepeating decimal.
Answer:
D
Step-by-step explanation:
Area of square=400sq.ft
or,l²=400sq.ft
or,l=(400sq.ft)½
or,l=(20²sq.ft)½
or,l=20ft
Thus,length of square is 20ft.
If length of square is increased by 1 ft then ,
New length=(20+1)ft=21ft
Area of square=(21ft)²
=441sq.ft

The sum of 3 consecutive odd integers is 33. Find the integers (n).
The integer(n) in the odd integers is 9.
How to find variables in equation?The sum of 3 consecutive odd integers is 33.
Odd integers are defined as any integers which cannot be divided by two. Therefore, odd integers includes 1, 3, 5, 7, 9, 11, 13 etc
Therefore, the integers can be found as follows:
let
n = first odd integer
n + n + 2 + n + 4 = 33
combine like terms
n + n + n + 2 + 4 = 33
3n + 6 = 33
subtract 6 from both sides of the equation
3n + 6 - 6 = 33 - 6
3n = 27
divide both sides by 3
n = 27 / 3
Therefore,
n = 9

Salesman Randy gets a fixed salary of $2000 per month and a commission of 2% on sale. If total sale is $30,000 for the month, find his total salary for the month?
Answer:
$2600
Step-by-step explanation:
If his monthly salary is $2000 and 2% commission.
He made $30,000 in sales for the month so lets make an equation.
s = total salary
s = $2,000 + .02($30,000)
s = $2,000 + $600
s = $2600
Randy's salary for the month is $2600.
