Suppose the midpoint of (AB) is M = (3,0). If point A has the coordinates of (-1,4), then what are the coordinates of B? (1,2)
(-5,8)
ОООО
(7,-4)
О (-4,4)

Step-by-step explanation:

Hey there!

Here;

The one end is A(-1,4) and midpoint M(3,0).

Let another endpoint be B(x,y).

Using midpoint formula.

Put all values.

Since, they are equal, equating with their corresponding elements we get.

6 = -1 +x

x= 7.

Again,

0 = 4+y

y = -4

Therefore the another endpoint is (7,-4).

So, answer is option C.

Hope it helps...

step-by-step explanation:

hope this

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
