Yessir I love math. I know you were being sarcastic but I love math. just multiply everything and you’ll get the answer
Answer:
6
Step-by-step explanation:
DB halves AC, i.e. AB = BC
I got X=11
Minus 7x on both sides
The equation the becomes :
-2x +179=157
Subtract 179 from both sides
Equation now is:
-2x= -22
Divide -2 on both sides
X= 11
Answer:
Step-by-step explanation:
Let the coordinate of the points W, V and R are and respectively.
The coordinate of the section point, which divides the line joining the two points and in the ration is
and
.
The given ration is,
.
The exact point can be determined by putting the value of the exact coordinate in the above-obtained formula.
The equation of a circle is (x - h)² + (y - k)² = radius²
where the center is represented by (h, k).
So to plug in:
(x - (-2))² + (y - 1)² = radius²
(x + 2)² + (y - 1)² = radius²
To find the radius, you can do the distance formula OR (and I suggest this one) use common sense. The center and point given have the same Y-value meaning they are in a horizontal line. Because of this, you can just find the distance between them (AKA your radius) by doing the absolute value of their difference:
|- 4 - (-2)| = |- 4 + 2| = |-2| = 2
Just to show order doesn't matter:
|- 2 - (-4)| = |- 2 + 4| = |2| = 2
Your radius is 2. Plug this into your equation and simplify.
(x + 2)² + (y - 1)² = (2)²
Your answer is:
(x + 2)² + (y - 1)² = 4
