2/3(x+6)=-18 I need the answer help me!!
iragen [17]

Answer:

x = -33

Step-by-step explanation:

2/3(x+6) = -18

multiply (x+6) by 2/3

2/3x + 4 = -18

subtract 4 from both sides

2/3x + 4 - 4 = -18 - 4

2/3x = -22

multiply by 3/2

2/3 x 3/2 x = -22 x 3/2

x = -33

Answer:

the center is (-4,7) and the radius is 3

Step-by-step explanation:

The center of a circle can be found using the equation (x-h)^2 + (y-k)^2 = r^2 and is (h,k) from it. Notice h and k are the opposite value as in the equation.  

First write the equation in this form.  

x^2 + 8x + ( ?)+ y^2 - 14y + (?) + 56 = 0  

Complete the square with each variable to find what numbers should go in place of the question marks.  

(8/2)^2 = 4^2 = 16  

(-14/2)^2 = -7^2 = 49  

Add 16 and 49 to both sides of the equation.  

x^2 + 8x + 16 + y^2 - 14y + 49 + 56 = 16 + 49\\(x+4)^2 + (y-7)^2 + 56 = 65\\(x+4)^2 + (y-7)^2 = 9  

So the center is (-4,7) and the radius is 3.

Answer:

Gain their trust back.  As someone who struggled with gaining trust I know that you just have to listen to them and gain it back.  Its going to be hard but I am also going into highschool next year.  For now tell them about your day and school work.  try and keep good grades because that will help you to slowly gain it back.  But if you do keep doing this bad stuff you went EVER get it back so for now just listen.  Having fun in highschool and having trust is so much better than fighting with your parents and not being allowed to do stuff.   And its going to take and long time so dont think that it will happen overnight.
