Find the standard form of the equation for the conic section represented by x^2 + 10x + 6y = 47.

Answers

Answer:

The standard form of the equation for the conic section represented by [tex]x^2\:+\:10x\:+\:6y\:=\:47[/tex] is:

[tex]4\left(-\frac{3}{2}\right)\left(y-12\right)=\left(x-\left(-5\right)\right)^2[/tex]

Step-by-step explanation:

We know that:

[tex]4p\left(y-k\right)=\left(x-h\right)^2[/tex] is the standard equation for an up-down facing Parabola with vertex at (h, k), and focal length |p|.

Given the equation

[tex]x^2\:+\:10x\:+\:6y\:=\:47[/tex]

Rewriting the equation in the standard form

[tex]4\left(-\frac{3}{2}\right)\left(y-12\right)=\left(x-\left(-5\right)\right)^2[/tex]

Thus,

The vertex (h, k) = (-5, 12)

Please also check the attached graph.

Therefore, the standard form of the equation for the conic section represented by [tex]x^2\:+\:10x\:+\:6y\:=\:47[/tex] is:

[tex]4\left(-\frac{3}{2}\right)\left(y-12\right)=\left(x-\left(-5\right)\right)^2[/tex]

where

vertex (h, k) = (-5, 12)

Answer:

9) no solution

10) p = 4

11) n = 2

12) x = 3

Step-by-step explanation:

9) -5 ( -v - 4) + 4v = v + 20

5v + 20 + 4v = v + 20

no solution

10) -2 -3(p + 3) = -4p - 7

-2 - 3p - 9 = -4p - 7

-11 = -1p - 7

-4 = -1p

p = 4

11) 4(3 - 4n) = -24 + 2n

12 - 16n = -24 + 2n

-18n = -36

n = 2

12) 4(4 - 3x) = -23 + x

16 - 12x = -23 + x

-13x = -39

x = 3

hope this helps! :)

Answer:

Number 11 Answer = n = 2 || Number 12 Answer = x = 3

Step-by-step explanation:

12) 4(4 - 3x) = -23 + x

1. multiply 4 times 4 and 4 times 3x

16 - 12x = -23 + x

2. subtract 16 from itself 16 and 23

-12x = -39 + x

3. subtract x from itself and -12x

-13x = -39

4. Divide -13 from itself and -39

x = 3

11) 4(3 - 4n) = -24 + 2n

1. multiply 4 times 3 and 4 times 4n

12 - 16n = -24 + 2n

2. subtract 12 from itself and 24

-16n = -36 + 2n

3. subtract 2n from itself and -16n

-18n = -36

4. Divide -18n from itself and -36

n = 2

Just a guess Bc I’ve no idea what you’re talking abt, but 3. Would set 30/6 and 15/y cross multiply, solve for y and get y =3
I think 3, because 15 is half of 30 and 3 is half of 6. Hope this helps

Step-by-step explanation:

I am not sure if you wanted to ask this

f(x) = 6^x becomes g(x)= (6^x ) -9 so it went DOWN 9 units
