Show that (0, 0) is equidistant from (1, 2), (-1, -2) and (2, 1).​

Mathematics

Len [333]2 years ago
3 0

Step-by-step explanation:

1) if (0;0) if point A, (1;2) is point B; (-1;-2) is C, (2;1) is D, then

2) the vector AB is (1;2); vector AC is (-1;-2) and vector AD is (2;1), then

3) the length of AB, AC and AD are:

|AB|=\sqrt{1^2+2^2}=\sqrt{5};

|AC|=\sqrt{(-1)^2+(-2)^2}=\sqrt{5};

|AD|=\sqrt{2^2+1^2}=\sqrt{5}.

4) if the lengths above are equal, then it means that (0, 0) is equidistant from (1, 2), (-1, -2) and (2, 1).

What is the solution to the following equation? -6(x-2) + 3x = -3(x + 3) + 21
NeX [460]

9514 1404 393

Answer:

  no solution

Step-by-step explanation:

Simplifying the given equation, you have ...

  -6(x -2) +3x = -3(x +3) +21 . . . . . given

  -6x +12 +3x = -3x -9 +21 . . . . . . eliminate parentheses

  -3x +12 = -3x +13 . . . . . . . . . . . . collect terms

  0 = 1 . . . . . . . . . . . . . add (3x-12) to both sides

There is no value of x that will make this true.

The equation has NO SOLUTION.

I would seriously appreciate if u helped me TvT
emmasim [6.3K]

Answer:

x=-11

Step-by-step explanation:

So we have the equation:

5+(x-2)=-8

Let's subtract 5 from both sides:

(5+(x-2))-5=(-8)-5

The left side will cancel. Subtract on the right:

x-2=-13

Now, add 2 to both sides:

(x-2)+2=(-13)+2

Again, the left side will cancel. Add the right:

x=-11

And we're done!
