Solve the following equations 4x + 3y =17 3x + 2y = 13

Mathematics

Answer:

(5,-1)

Step-by-step explanation:

4x+3y=17

3x+2y=13

So elimination sounds fun but we will have to do manipulation:

Multiply top equation by 2 and bottom equation by 3. This will cause the second term in both by 6y which means we would be setup for elimination.

8x+6y=34

9x+6y=39

--------------------now subtract the equations

-x+0=-5

So x=5

Now plug it into either question (no matter which-pick and choose)

I will go with the second original 3x+2y=13

So if x=5 we have 15+2y=13

Subtract 15 on both sides:        2y=-2

Now divide both sides by 2:      y=-1

Answer (5,-1)

Which undefined term is used to define an angle?<br><br> line<br> plane<br> point<br> ray
Afina-wow [57]

The Undefined term that is used to define an angle is a point.

<h2>Further Explanation: </h2><h3>Angle</h3>
  • An angle is defined as the union of two rays with a common endpoint.
  • The common end point is known as the vertex of the angle while the rays are known as the sides of the angle.
<h3>A ray  </h3>

It is a part of a line with one end point and proceeds on in one direction.

<h3>Naming of angles</h3>
  • Angles can be named in three different ways;
  1. Using three Capital letters such as ∠ PQR, or ∠BCD. The middle letter represents the vertex of the angle. Therefore, the angles above are read as "angle PQR" and angle BCD.
  2. Using the Vertex of the angle. For example, in the case of ∠PQR, can also be called angle Q, while ∠BCD can be called angle C.
  3. Angles can also be named by placing any number or symbol at the vertex in the interior of the angle. Such that angles can be called angle 1 or angle 3 , or angle 5, and so on.
  • Angles are measured using a tool known as a protractor
<h3>Measuring of an angle using a protractor</h3>
  • To measure the angle, the mid-point of a protractor is placed on the vertex of the angle.  
  • Then lining up one side of the angle with the zero line of the protractor.  
  • Then read the degrees where the other side crosses the number scale.
