A(4, -1), B(3, 8), C(-1, 1); y = -2
Answers
Answer:
Point A: (4, -3)
Point B: (3, -12)
Point C: (-1, -5)
Step-by-step explanation:
Reflection of point A:
The x will stay the same and only the y will change.
Take the y-coordinate and subtract it from the reflection line while getting the absolute value..
|(-1) - (-2)| = |1| = 1
This means, point A is one unit down the line y = -2
(-2) - 1 = -3
The coordinate for A will now be (4, -3).
Reflection of point B:
Again, the x will stay the same and only the y will change.
Using the absolute value, get the y-coordinate and subtract it from the reflection line again..
|(8) - (-2)| = |10| = 10
This means, point A is five unit down the line y = -2
(-2) - 10 = -17
The coordinate for B will now be (3, -12).
Reflection of point C:
I think you get the gist of it.
|(1) - (-2)| = |3| = 3
(-2) - 3 = -5
The coordinate for C will now be (-1, -5).
I added an image down below of what the reflection looks like. Sometimes it helps to see things visually.
The red triangle is the original image and the blue triangle is the image after the reflection. The purple line is the reflection line y = -2
Hope this helped!

PLEASE HELP!!! A line y=mx+b passes through point (−4, 6) and is perpendicular to y=−12x+6.
What is the value of b?
Answers
Answer:
Improper fraction: 19/3
Mixed number: 6 1/3
Step-by-step explanation:
If these two lines are perpendicular, their slopes are negative reciprocals of each other. The line would be something like:
y = (1/12)x+b
So plug in the coordinate values.
6 = (1/12)(-4)+b
6 = (-1/3)+b
6 1/3 = b

You want a new sound system to go with your new television. If you saved $30 for the sound bar that had a 21% discount. What was the original price of the sound bar before the discount?
Answers
Answer:
$142.86
Step-by-step explanation:
In order to know the original price of the sound bar, it is best to write the problem above into a mathematical sentence first.
Given: $30 = the amount you were able to save
21% = the discount (this means that $30 is the 21% discount)
Let x be the original price of the sound bar.
The mathematical sentence is:
$30 is 21%(0.21) of x
x=[tex]\frac{30}{0.21}[/tex]
x= $142.857 or $142.86 (once rounded off to the nearest hundredths)
So, the original price of the sound bar before the discount is $142.86

For every left-handed person, there are about 4-right handed people. If there are 30 students in a class, predict the number of students who are right-handed.
Answers
Answer:
There are 24 right handed students
Step-by-step explanation:
This is a ratio question so it would be represented as 1:4.
First you would do 1 + 4 which is 5.
Then do 30 ÷ 5 which is 6.
Finally multiply 6 by 4 and 1.
So 6 × 4 × 1 is 24.
So there are 24 students who are right handed.

Laura spent 4.1 more hours on her project than Alexander spent on his. If we split each number into 2 parts (like this: 12.5 -> 12 and .5; 16.6 -> 16 and .6) then we can subtract 12 from 16 and .5 from .6 to get 4 and .1. we add those together to get 4.1

so the width will be 4L
the formular for the perimeter of a rectangle is =2(L +W)
170=2(L +4L)
170=2(5L)

Out of 60 applicants to a university, 40 are from the East. If 20 applicants are to beselected at random, find the probability that:
a. 10 are from East.
b. Not more than 2 are from East.
Answers
Answer:
a. 40С10 * 20С10 / 60С20
b. 1 + (40)(20) + (40C2)(20C2) / 60С20
Step-by-step explanation:
Total number of application = 60
Total number of application from east = 40
Total number of application remaining = 20
Number of ways of selecting 20 applicant = 60C20 (Sample space)
a. Probability of 10 are from East.
= (10 from east) * (10 from remaining)
= 40С10 * 20С10 / 60С20
b. Probability of Not more than 2 are from East.
= P(x≤2)
= P(x=0) + P(X=1) + P(X=2)
= [40С0 * 20С20 / 60С20] + [40С1 * 20С19 / 60С20] + [40С2 * 20С18 / 60С20]
= 1 + (40)(20) + (40C2)(20C2) / 60С20
