23=7/9 (6x-36)+9 Solve for x

1 answer:

3 0

23 = 7/9(6x - 36) + 9

23 = 7(6x - 3)/9 + 9

23 = 42(x - 6)/9 + 9

23 = 14(x - 6)/3 + 9

14 = 14(x - 6)/3

42 = 14(x - 6)

3 = x - 6

9 = x

x = 9

hope that helps, God bless!

Answer:

HEY YOU! Yes, you, sitting behind your screen reading this. I don't know you and you certainly don't know me. But I want to tell you something. Everyone has their own story. Yours might be filled with joy and happiness, or it might be clouded with pain and misfortune. I want you to know that you're a beautiful, wonderful, talented person. Even if your life isn't going the way you want it to right now, I know that you'll be able to make it out alright. I want you to do me a favor. I know I'm just a stranger, but just trust me, okay? Every time you see your reflection, be it in the mirror in the bathroom, in a window somewhere, or in a puddle on the street, I want you to look at yourself and give yourself a hug. Because even if you aren't the prettiest or the smartest or the funniest, you're something that no one else can be: you. And you are the greatest thing you can be. Smile at strangers. Be confident in yourself. Cry when you feel like crying, laugh when you feel like laughing. Treat yourself like a god/goddess because you deserve it. Hold your head up and keep your heart open. You're worth everything and then some. And always remember that no matter what, even if it doesn't seem like it, you're everything to someone. I was bullied for so long and was told that I wasn't beautiful, and it broke me down. But I realized that I am beautiful and so is everyone else. I wanted to make sure no one felt upset like I did

Help! locus points!

Liula [17]

Answer:

Circle X with radius 2 cm.
Either of two lines parallel to AB.

Step-by-step explanation:

1. The definition of a circle is all the points in a plane that are at some radius r from a given point (the circle center). That is what you have, with a radius of 2 cm.

2. Parallel lines are the same distance apart everywhere. Each line will have two parallel lines at some given distance from it, one on each side. Here, the separation distance from AB is 1 cm, so your locus of points is the two lines parallel AB that are 1 cm from it on either side.

Find an equation of the plane tangent to the following surface at the given point. 8 xy plus 5 yz plus xzminus56equals0; (2 com

Nimfa-mama [501]

The Question is :

Find an equation of the plane tangent to the following surface at the given point.

8xy + 5yz + xz - 56 = 0; (2, 2, 2 )

The equation of the tangent plane at (2, 2, 2 ) is 0.

Answer:

The equation of the plane tangent to the surface

8xy + 5yz + xz - 56 = 0

at the point (2, 2, 2 )

is 9x + 13y + 6z - 56 = 0

Step-by-step explanation:

Given the equation

8xy + 5yz + xz - 56 = 0

and the point

(2, 2, 2 ).

To find the equation of the plane tangent to the surface, we first differentiate the given function with respect to x, y and z respectively.

F_x = 8y + z

F_y = 8x + 5z

F_z = 5y + x

At the point (2, 2, 2)

F_x = 18

F_y = 26

F_z = 12

The equation of the plane is given as

(F_x)(x - 2) + (F_y)(y - 2) + (F_z)(z - 2) = 0

18(x - 2) + 26(y - 2) + 12(z - 2) = 0

18x + 26y + 12z - 36 - 52 - 24 = 0

18x + 26y + 12z - 112 = 0

Divide through with 2

9x + 13y + 6z - 56 = 0

This is the equation we are looking for.
