Use a coordinate proof to prove that mid segment mn of triangle pqr is parallel to pr and half the length of pr. which is the first best step? a. place the triangle on a coordinate grid such that vertex p is at the origin, and pr lies on x-axis. b. place the triangle on a coordinate grid such that vertex p is on y-axis and vertex r us on the x-axis
Please consider marking brainliest! :)
Place the triangle on a coordinate grid such that QR lies on the x-axis and PQ lies in the y-axis. Therefore, option D is the correct answer.
If we start with Step A, we are unknown about points Q and R and these two points need to be located somewhere.
If we start with step B, we are unknown about point Q and it needs to be located.
If we start with step C, we are unknown about points P and R, and these two points need to be located.
Let us start with step D,
It is given that,
In triangle PQR, QR lies on the x-axis while PQ lies on the y-axis means Q will be at the origin
Coordinates of Q will be (0, 0)
Let us take coordinates of R (4, 0) and P as (0, 4)
Let us take the midpoints of PQ &PR as ‘S’ & ‘T’ respectively.
Now, coordinates of S and T can be found using the Mid-Point formula
Coordinates of mid-point = (x₁+x₂)/2, (y₁+y₂)/2
Coordinates of S= (2, 0)
Coordinates of T= (2, 2)
Here,
We have to prove ST= QR/2 and ST Parallel to QR.
(1) Now, using distance formula,
ST = √([(0-2)²+(2-2)²])
ST = 2 (1/2 ×QR)
(2) Now, in order to prove ST is parallel to QR, we need to prove that the slope of ST is equal to the slope of QR.
Using slope formulae
Slope of ST = (2-2)/(2-0) = 0
Slope of QR = 0, as we know slope of x-axis is 0.
So, the value of ST is half of QR as well as it is parallel to QR.
Therefore, step D is the best option to start with.

Answer: (2, -2)
x=2, y=-2
Answer:
(2, -2)
Step-by-step explanation:
4x + y = 6
x - 2y = 6
x = 2y + 6
4(2y + 6) + y = 6
8y + 24 + y = 6
9y + 24 = 6
9y = 6 - 24
9y = -18
y = -18 ÷ 9
y = -2
4x + (-2) = 6
4x - 2 = 6
4x = 6 + 2
4x = 8
x = 8 ÷ 4
x = 2
Confirm:
4x + y = 6
4(2) - 2 = 6
8 - 2 = 6
6 = 6 (Correct)

The sum of 555 consecutive odd numbers is 135135135.
Answers
I'm guessing you mean to say that sum of 5 consecutive odd numbers is 135. In that case, let x be the first number. Then
x + (x + 2) + (x + 4) + (x + 6) + (x + 8) = 135
5x + 20 = 135
5x = 115
x = 23
So the numbers are 23, 25, 27, 29, and 31.
If you really did mean 555 consecutive odd numbers summing to 135,135,135, the process is the same, but you would find a non-integer solution so that wouldn't be possible.

For which mapped relation is the domain
{1,2,3}{1,2,3}?
Answers
Answer :C
Step-by-step explanation: For any given function, all first input values (x-values/coordinates) in the relation are considered as the domain values. While the output values (y-values/coordinates) make up the range of the given function.
The mapped relation that has a domain of {1,2,3}, is the mapped relation that has 1, 2, and 3 on the input side on our left.
Therefore, the mapped relation in option C is the answer.

One morning, Muhammad's deli shop sells 15 sandwiches in 10 minutes. If the shop continues to sell sandwiches at the same rate, about how many sandwiches will the shop sell in 3/4 of an hour?
Answers
Answer:
68 sandwiches
Step-by-step explanation:
Given that,
A shop sells 15 sandwiches in 10 minutes.
10 minutes = (10/60) hour = (1/6) hour
In (1/6) hour shop sells 15 sandwiches
In 1 hour = 90 sandwiches
To find, no of sandwiches in 3/4 hours, multiply 3/4 by 90. So,
In 3/4 hour = [tex]90\times \dfrac{3}{4}=67.5[/tex] sandwiches
or
≅ 68 sandwiches
So, 68 sandwiches can be made in 3/4 hour.

Answers
Answer: 90 degrees counterclockwise and 270 degrees clockwise are the same things and you need to use the same formula for both
Step-by-step explanation:We swap the value of x and y and negate the value of y. So the value of x becomes the value of y and value of y becomes the value of x. so the formula is:
(x, y) –> (-y, x)
Before Rotation After Rotation
(x, y) (-y, x)

43x−4=5−x
Step 1: Simplify both sides of the equation.
43x−4=5−x
43x+−4=5+−x
43x−4=−x+5
Step 2: Add x to both sides.
43x−4+x=−x+5+x
73x−4=5
Step 3: Add 4 to both sides.
73x−4+4=5+4
73x=9
Step 4: Multiply both sides by 3/7.

Harper is a salesperson who sells computers at an electronics store. She makes a base pay amount of $100 per day regardless of sales and she earns a commission of 1% of the dollar amount of all sales that she makes. Write an equation for P,P, in terms of x,x, representing Harper's total pay on a day on which she sells xx dollars worth of computers.
Answers
Given:
Base pay = $100 per day
Commission = 1% of the dollar amount of all sales that she makes
To find:
The equation representing Harper's total pay on a day.
Solution:
Let P be the Harper's total pay on a day if she sells x dollars worth of computers.
Commission on x dollars sales = 1% of x = 0.01x
Total pay = Base pay + Commission
[tex]P=100+0.01x[/tex]
Therefore, the required equation is [tex]P=100+0.01x[/tex].
