Complete the square please.

Answer:

(x-3)^2 + (y+2)^2 = 9^2

Step-by-step explanation:

x^2 -6x+y^2+4y-68 = 0

Complete the square

x^2 -6x+y^2+4y-68+68 = 0+68

x^2 -6x+y^2+4y = 68

Find the term to add for x

-6 /2 = -3  -3^2 = 9

Find the term to add for y

4/2 =2  2^2 = 4

Add 9 and 4

x^2 -6x+9+y^2+4y+4 = 68+9+4

(x-3)^2 + (y+2)^2 = 81

(x-3)^2 + (y+2)^2 = 9^2

The standard form is

(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius

PLEASE HELP IM DESPERATE WILL GIVE BRAINLIEST ONLY ANSWER IF YOU ARE HELPING
VARVARA [1.3K]

Answer:

48

Step-by-step explanation:

u • w

= (i + 6j ) • (9i - 2j )

= (1 × 9 ) + (6 × - 2 )

= 9 + (- 12)

= 9 - 12

= - 3

v • w

= (5i - 3j ) • (9i - 2j )

= (5 × 9) + (- 3 × - 2)

= 45 + 6

= 51

Then

u • w + v • w

= - 3 + 51

= 48

On a coordinate plane, two parabolas open up. The solid-line parabola, labeled f of x, goes through (negative 2, 4), has a verte
34kurt

Answer:

y = (x+4)^{2}+6

Step-by-step explanation:

The parabola with vertex at point (h,k) is described by the following model:

y - k = C\cdot (x-h)^{2}

The equation which satisfies the conditions described above:

y - 6 = (x+4)^{2}

y = (x+4)^{2}+6

The two points are evaluated herein:

x = -6

y =(-6+4)^{2}+6

y = (-2)^{2}+6

y = 4 + 6

y = 10

x = -2

y = (-2+4)^{2}+6

y = 2^{2} + 6

y = 4 + 6

y = 10

The equation of the translated function is y = (x+4)^{2}+6.
