Answer:

x = 1

y = -2

Step-by-step explanation:

adding both quation we get

3x -2y + x + 2y =7 + -3

4x = 4

x = 1

substituting this equation in the earlier equation we get

3 * 1 -2y = 7

3 - 2y = 7

-2y = 4

y = -2

Answer:

  • x=1
  • y= -2

Step-by-step explanation:

  • 3x-2y =7
  • x+2y= -3
  • 4x=4
  • x=4/4
  • x=1
  • 3x-2y=7
  • 3(1)-2y=7
  • 3-2y=7
  • -2y=7-3
  • -2y=4
  • 2y=-4
  • y=-4/2
  • y= -2
  • Verify solution
  • x+2y= -3
  • 1+2y= -3
  • 2y=-3-1
  • 2y= -4
  • y= -4/2
  • y= -2

Triangle PQR and STR are shown. Which of the following does Not justify PQR ~STR ?​
hjlf

The equation that does not justify the similarities of both triangles is:

\frac{RQ}{RT}= \frac{PQ}{ST}

<h3>Similar triangles</h3>

Similar triangles may or may not have congruent sides.

The triangles are given as:

  • Triangle PQR
  • Triangle STR

The above means that, the following sides are similar

  • Line segments PQ and ST
  • Line segments QR and TR
  • Line segments PR and SR

So, the equation that does not justify the similarities of both triangles is:

\frac{RQ}{RT}= \frac{PQ}{ST}

How many triangles can be formed with segments measuring 4. 7 m, 1. 6 m, and 2. 9 m? none one more than one.
Svet_ta [14]

The sum of the length of the two sides of the triangle must be greater than the length of the third side. None of the triangles is formed. Then option A is correct.

<h3>What is the triangle?</h3>

Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.

The sides of the triangle are 4.7 m, 1.6 m, and 2.9 m.

The condition will be

1.6 + 2.9 \ngtr  4.7

We know that the sum of the length of two sides of the triangle must be greater than the length of the third side.

Hence, none of the triangles is formed.

Thus, option A is correct.

More about the triangle link is given below.
