the midpoint is AB is M(3,-2). One endpoint is A(7,-9). Find the coordinates of the other endpoint B.

cestrela7 [59]

Answer:

The required points of the given line segment are ( - 1, - 5 ).

Step-by-step explanation:

Given that the line segment AB whose midpoint M is ( 3, -2 ) and point A is ( 7, - 9), then we have to find point B of the line segment AB -

As we know that-

If a line segment AB is with endpoints ( $x_{1}, y_{1}$ ) and ( $x_{2}, y_{2}$ )then the mid points M are-

M = ( $\frac{ x_{1} + x_{2} }{2}$ , $\frac{ y_{1} + y_{2} }{2}$ )

Here,

Let A ( 7, - 9 ), B ( x, y ) with midpoint M ( 3, - 2 ) -

then by the midpoint formula M are-

( 3, - 2 ) = ( $\frac{ 7 + x}{2}$ , $\frac{ - 9 + y}{2}$ )

On comparing x coordinate and y coordinate -

We get,

( $\frac{ 7 + x}{2}$ = 3 , $\frac{ - 9 + y}{2}$ = - 2)

( 7 + x = 6, - 9 + y = - 4 )

( x = 6 - 7, y = - 4 + 9 )

( x = - 1, y = -5 )

Hence the required points A are ( - 1, - 5 ).

We can also verify by putting these points into Midpoint formula.

In circle O, AC and BD are diameters.

Snezhnost [94]

Because AC is a diameter we can find the 180/3 = x

giving us the x= 60

Then that arc AB = 120

Help and ill give brainliest

Furkat [3]

Answer:

No, it isnt a solution

Step-by-step explanation:

Even though it works for one equation, it doesnt work on the other. You have to have the solution work for both equations so that it can be a true solution. Hope this helps you understand!

What is 2/3 times 7 wholes

Romashka-Z-Leto [24]

2/3 times 7 wholes is the same was 7 because 1 whole is 1.
What would you do it multiply the numerator and numerator so the would be 2x7. Then we would multiply the denominators. 3x1=1. Therefore the answer is 14/3.

I will give brainliest to the right answer!! Find the vertex and the length of the latus rectum. x= 1/2 (y - 5)² + 7

MAXImum [283]

Answer:

(7, 5)
2

Step-by-step explanation:

When the quadratic is written in vertex form:

x = a(y -k)^2 +h

the vertex is (x, y) = (h, k), and the length of the latus rectum is 1/a.

For your given equation, ...

x = (1/2)(y -5)^2 +7

you have a=1/2, k = 5, h = 7, so ...

the vertex is (7, 5)

the length of the latus rectum is 1/(1/2) = 2
