Point M is the midpoint of AB. The coordinates of point A are (−7, 1) and the coordinates of M are (−2, 2). What are the coordin
notka56 [123]

Answer:

\huge{\boxed{\sf{ ( 3 , 3 ) }}}

Step-by-step explanation:

Co-ordinates of point A = ( -7 , 1 )

Co-ordinates of point M = ( -2 , 2 )

Let the co-ordinates of point B be ( x , y )

A ( -7 , 1 ) \longrightarrow ( x1 , y1 )

B ( x , y ) \longrightarrow ( x2 , y2 )

Now,

Midpoint = (\frac{x1 + x2}{2}  , \frac{y1 + y2}{2} )

⇒( -2 , 2 ) = ( \frac{-7 + x}{2}  , \frac{1 + y}{2} )

Finding the value of x :                    

⇒-2 = \frac{-7 + x}{2}

Do cross multiplication                

⇒-4 = -7 + x

⇒-7 + x = -4

⇒x = -4 + 7

⇒x = 3

Now, finding the value of y

⇒2 = \frac{1+y}{2}

Do cross multiplication

⇒4 = 1+y

⇒1+y = 4

⇒y = 4 - 1

⇒y = 3

Hence, The co-ordinates of point B = ( 3 , 3 )

Hope I helped!

Best regards!

What is the next three terms to a sequence -1/3125, 1/625, -1/125, 1/25
Natali [406]

Answer:

-1/3125, 1/625, -1/125, 1/25 , -(1÷5) , 1 , -5

Step-by-step explanation:

1÷625÷(-1÷3 125) = -5

-1÷125÷(1÷625) = -5

(1÷25)÷(-1÷125) = -5

Then the common ratio of the geometric sequence is -5 then we keep multiplying by -5 each time to get the next term:

(1÷25)×(-5) = -(1÷5)

-(1÷5)×(-5) = 1

(1)×(-5) = -5
