Answer:

The answer is A.1

Step-by-step explanation:  3(x + 1) = −2(x − 1) + 6 is turned into 3+3=−2 +2+6 once it is distributed.

then when you add the numbers you get  3+3=−2 +8

Then subtract 3 from both sides of the equation.Then simplify and add 2x to both sides and combine the like terms.

Finally your left with 5x=5 then divide and you get 1.

PLEASE HELP, please write it out in the system of equations (step by step)
gizmo_the_mogwai [7]

Answer:

{x,y}={-2,3}

Step-by-step explanation:

[1]    2x + y = -1

  [2]    x - 2y = -8  <------- given linear equations

Graphic Representation of the Equations : ----> given in attatchment

y + 2x = -1        -2y + x = -8  < ----- point where they connect is shown in graph

Solve by Substitution :

// Solve equation [2] for the variable  x

 [2]    x = 2y - 8

// Plug this in for variable  x  in equation [1]

  [1]    2•(2y-8) + y = -1

  [1]    5y = 15

// Solve equation [1] for the variable  y

  [1]    5y = 15

  [1]    y = 3

// By now we know this much :

   x = 2y-8

   y = 3

// Use the  y  value to solve for  x

   x = 2(3)-8 = -2

Solution :

{x,y} = {-2,3}

10 points!!! Please answer 8 and 9 and hurry
lilavasa [31]

Answer:

Step-by-step explanation:

since EG bisects angle DEF

31 = x + 15

31 - 15 = x

x = 16 degree

6x - 4 = 56

6x = 56 + 4

x = 60/6

x = 10
