Svetach [21]2 years ago
4 0

<u>Given Equation</u>:-

  • 5x+y=17 . . . . . . . . 1
  • x+y=3 . . . . . . . . . . 2

<u>To find</u> :

  • value of x
  • value of y

<u>Solution</u> :

<u>Let's start with equation 2</u>:-

x + y = 3

y = 3 - x

Put the value of y in Equation 1

  • 5x+y=17
  • 5x + (3 - x) = 17
  • 5x - x + 3 = 17
  • 4x + 3 = 17
  • 4x = 17 - 3
  • 4x = 14
  • x = 14/4
  • x = 7/2
  • x = <em>3.5</em>

<u>Now Let's find value of y</u><u>:</u>

put the value of x in equation 2:

y = 3 - x

y = 3 - 3.5

y = <em>0.5</em>

Find the perimeter of the triangle with coordinates A(5,2), B(5,4), and C(1,1). Round to the nearest tenth.
faltersainse [42]

Answer:

11.1 units

Step-by-step explanation:

We solve for this using the formula when using coordinates (x1 , y1) and (x2, y2)

= √(x2 - x1)² + (y2 - y1)²

A(5,2), B(5,4), and C(1,1).

For AB = √(x2 - x1)² + (y2 - y1)²

= A(5,2), B(5,4)

= √(5 - 5)² +(4 - 2)²

= √ 0² + 2²

= √4

= 2 units

For BC = √(x2 - x1)² + (y2 - y1)²

= B(5,4), C(1,1)

= √(1 - 5)² +(1 - 4)²

= √ -4² + -3²

= √16 + 9

= √25

= 5 units

For AC = √(x2 - x1)² + (y2 - y1)²

A(5,2), C(1,1)

= √(1 - 5)² + (1 - 2)²

= √-4² + -1²

= √16 + 1

= √17

= 4.1231056256 units

The Formula for the Perimeter of Triangle = Side AB + Side BC + Side AC

= 2 units + 5 units + 4.1231056256 units

= 11.1231056256 units.

Approximately the Perimeter of a Triangle to the nearest tenth = 11.1units
