Solve by elimination 5x-14y=22 -6x+7y=3
Airida [17]
5x - 14y = 22 ⇒   5x - 14y = 22
-6x + 7y =  3  ⇒ <u>12x - 14y = -6</u>
                                    <u>-7x</u> = <u>28</u>
                                     -7     -7
                                       x = -4
                            5x - 14y = 22
                         5(-4) - 14y = 22
                           -20 - 14y = 22
                         <u>+ 20           + 20</u>
                                  <u>-14y</u> = <u>42</u>
                                  -14    -14
                                       y = -3
                                  (x, y) = (-4, -3)

Y=2x^2+12x+14 in vertex form
balandron [24]

Answer:

y = 2(x + 3)² - 4

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Using the method of completing the square

y = 2x² + 12x + 14 ← factor out 2 from the first 2 terms

  = 2(x² + 6x) + 14

To complete the square

add/subtract ( half the coefficient of the x- term)² to x² + 6x

y = 2(x² + 2(3)x + 9 - 9 ) + 14

  = 2(x + 3)² - 18 + 14

  = 2(x + 3)² - 4 ← in vertex form
