HELP!!!!!
SCORPION-xisa [38]

Answer:

  1, 5, 2, 4, 3, 7, 6

Step-by-step explanation:

After dividing by the leading coefficient, each equation can be put into the form ...

  x² + y² + ax +by +c = 0

Subtracting c and separately completing the square for x-terms and y-terms, we get ...

  x² + ax + (a/2)² + y² + by + (b/2)² = -c + (a/2)² + (b/2)²

  (x +a/2)² + (y +b/2)² = r² = (a/2)² + (b/2)² -c . . . . . rewrite in standard form

Ordering by the square of the radius length will match the ordering by radius length, so we just need to compute (a/2)² +(b/2)² -c for each given equation. I find it convenient to let a calculator or spreadsheet do this calculation (see attached).

In the order the equations are given, the square of the radius is ...

  3, 18, 45, 23, 5, 117, 46

So the order of the equations from smallest radius to largest is ...

  1, 5, 2, 4, 3, 7, 6

add the term that makes the given expression into a perfect square. write the result as the square of a bracketed expression c s
Molodets [167]
<h2>Perfect Squares</h2>

Perfect square formula/rules:

  • a^2+2ab+b^2=(a+b)^2
  • a^2-2ab+b^2=(a-b)^2

Trinomials are often organized like ax^2+bx+c.

The <em>b</em> value in this case is <em>c</em>, and it will always equal the square of half of the <em>b</em> value.

  • Perfect square trinomial: ax^2+bx+(\dfrac{b}{2})^2
  • or ax^2-bx+(\dfrac{b}{2})^2

<h2>Solving the Question</h2>

We're given:

  • c^2-4c

In a trinomial, we're given the ax^2 and bx values. <em>a</em> in this case is 1 and <em>b</em> in this case is 4. To find the third value by dividing 4 by 2 and squaring the quotient:

  • 4 ÷ 2 = 2
  • 2² = 4

Therefore, the term that we can add is + 4.

c^2-4c+4

To write this as the square of a bracketed expression, we can follow the rule a^2-2ab+b^2=(a-b)^2:

(c-2)^2

<h2>Answer</h2>

c^2-4c+4

(c-2)^2

Keith_Richards [23]

Answer:

Find the slope by first creating two points in the form (years, salary)

(0, 66640) ; (8, 73400)

calculate the slope using the correct slope formula

m = (73400 - 66640)/(8 - 0) = 6760/8 = 845
