What are the coordinates of point C
Not sure if I’m right or wrong

Answers

Answer: (0, -6)

Step-by-step explanation: When finding the coordinates of a given point, be very careful with your signs.

On the x-axis, left means negative and right means positive and

on the y-axis, down means negative and up means positive.

So to find the coordinates for point C, we start at the origin

which is where the x-axis and y-axis intercept.

So, we go 0 units to the left or right and 6 units down.

So that's (0, -6).

Remember that the first number in the ordered pair represents the x-coordinate or how far we move to the left or right from the origin and the second number represents the y-coordinate or how far we move up or down from the origin.

Answer:

x always comes first so that is 0

then it is y and that is -6 so the answer is (0,-6) aka B

What is the solution of the system of equations: -2x+8y=-8 and 5x-8y=20 using elimination​

Answers

Answer:

x = 4 and y = 0

Step-by-step explanation:

Given expression:

         -2x + 8y = -8

           5x - 8y = 20

Now, to solve this problem by elimination, follow this procedure:

           -2x + 8y = -8     --- i

            5x - 8y = 20      --- ii

 Coefficient of y in both expression have similar values;

  Now, add equation i and ii;

         (-2x + 5x) + (8y -8y ) = -8 + 20

                3x = 12

  Divide both sides by 3;

                 x = (12)/(3) = 4

Now, to find y; put x = 4 into equation i,

              -2(4) + 8y = -8

                -8 + 8y = -8

      Add +8 to both sides of the expression;

                -8 + 8 + 8y = -8 + 8

                              8y = 0

                                 y = 0

In the diagram shown, M, N and P are collinear and QM=QN as shown. If mMQN = 48" andmNQP = 33. Justify why QNP must be isosceles.

Answers

An isosceles triangle is that the triangle must have two sides of equal length.

Triangle QNP is isosceles triangle because, QN = PN

In triangle QMN,  

        Since,  QM = QN

 So,  ∠QMN = ∠QNM

By property of triangle:

∠MQN + ∠QNM + ∠QMN = 180

   48 + 2 ∠QNM = 180

              ∠QNM = (180-48)/(2) = 66  degree

  So, ∠QMN = ∠QNM = 66 degree

from figure,

    ∠QNM + ∠QNP = 180

                    ∠QNP = 180 - 66 = 114 degree.

In triangle QNP,  

              ∠QNP + ∠PQN + ∠QPN = 180

                        ∠QPN = 180 - 33 - 114 = 33 degree

Since,     ∠QNP = ∠QPN = 33 degree

Therefore, triangle QNP is isosceles triangle.

Answer/Step-by-step explanation:

Let's find the measure of the angles of ∆QNP.

∆QMN is am isosceles ∆, because it has two equal sides. Therefore, its base angles would be the same. Thus:

m<MNQ = ½(180 - 48) (one of the base angles of ∆QMN)

m<MNQ = ½(132) = 66°

Next, find m<QNP

m<QNP = 180° - m<MNQ (linear pair angles)

m<QNP = 180° - 66° (Substitution)

m<QNP = 114°

Next, find m<P

m<P = 180 - (m<QNP + m<PQN) (sum of ∆)

m<P = 180 - (114 + 33)

m<P = 180 - 147

m<P = 33°

Thus, in ∆QNP, there are two equal angles, namely, <P and <PQN.

An isosceles ∆ had two equal base angles. Therefore, ∆QNP must be an isosceles ∆.
