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)

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:

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.

Answer:

[tex]x=\frac{30}{7}[/tex]

Step-by-step explanation:

Step 1: Subtract 10 from both sides.

−7x+10 −10= −20 -10

−7x=−30

Step 2: Divide both sides by -7.

−7x /−7  =  −30 /−7

x= 30 /7

Answer:

Step-by-step explanation:

-5x + 10 > -15 is your original equation.

You need to isolate the x variable.

Start by subtracting 10.

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].

Answer:

A small pizza cost $12.99

Answer:

The price of a small pizza is 12.99

Step by step explanation:

15.75 + 17.50 + ? = 46.24

15.75 + 17.50 = 33.25

46.24 - 33.25 = 12.99

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.

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)
