3x + 2y = 2

Mathematics
1 answer:

3x + 2y = 2,    -2x + y = 8

Let us just solve by testing each of the options.

Option A is (-2, 4), that is x =-2 and y = 4

check:        for x = -2 and y = 4

3x + 2y = 2               

3*-2 + 2*4

-6 +  8 = 2

2 = 2

So both sides are equal.

-2x + y = 8              x = -2 and y = 4

-2*-2 + 4

4 + 4

8

8 = 8

Since option A (-2, 4) satisfies both equation, no need to test other options.

Option A is the answer.

M∠Q = <br> m∠R = <br> m∠S = <br><br> 40 POINTS!!!!!!!
Marizza181 [45]

9514 1404 393

Answer:

  ∠Q = 89°

  ∠R = 123°

  ∠S = 91°

Step-by-step explanation:

It seems easiest to start by finding the measures of each of the arcs. The measure of an arc is double the measure of the inscribed angle it subtends.

  arc QRS = 2·∠P = 114°

So, ...

  arc QR = arc QRS - arc RS = 114° -41° = 73°

The total of the arcs around the circle is 360°, so ...

  arc PQ = 360° -arc PS -arc QRS

  arc PQ = 360° -137° -114° = 109°

__

  ∠Q = (1/2)(arc RS + arc PS) = (1/2)(41° +137°)

  ∠Q = 89°

__

  ∠R = (1/2)(arc PS +arc PQ) = (1/2)(137° +109°)

  ∠R = 123°

__

  ∠S = (1/2)(arc PQ +arc QR) = (1/2)(109° +73°)

  ∠S = 91°
