Answer:

x=-1

Explanation:

-6+5(1-x)=-3-7x

We move all terms to the left:

-6+5(1-x)-(-3-7x)=0

We add all the numbers together, and all the variables

5(-1x+1)-(-7x-3)-6=0

We multiply parentheses

-5x-(-7x-3)+5-6=0

We get rid of parentheses

-5x+7x+3+5-6=0

We add all the numbers together, and all the variables

2x+2=0

We move all terms containing x to the left, all other terms to the right

2x=-2

x=-2/2

x=-1

Answer:

x= -1

Step-by-step explanation:

1. Expand

-6+5 (1-x) : -5x-1

-5x - 1 = -3 - 7x

2. Add 1 to both sides

-5x - 1 + 1 = -3 -7x + 1

3. Simplify

-5x = -7x -2

4. Add 7x to both sides

-5x + 7x = -7x -2 + 7x

5. Simplify

2x = -2

6. Divide both sides by 2

2x/2 = -2/2

7. Simplify

x=-1

Hope this helped :)

What is the other endpoint if one endpoint is (10,12) and the midpoint is (6,9).?

Lubov Fominskaja [6]

Answer:

$(2,\, 6)$ .

Step-by-step explanation:

Let $(x_{0},\, y_{0})$ and $(x_{1},\, y_{1})$ denote the two endpoints.

The formula for the midpoint of these two points would be:

$\displaystyle \left(\frac{x_{0} + x_{1}}{2},\, \frac{y_{0} + y_{1}}{2}\right)$ .

(Similar to taking the average of each coordinate.)

In this question, it is given that $x_{0} = 10$ whereas $y_{0} = 12$ . Substitute these two values into the expression for the coordinate of the midpoint:
