Helpp me in geometry please
LekaFEV [45]
Hi there !

You have a formule. You just have to apply it.

Let's do it then !

First of all, you must write the coordinates of the point E and F.

Therefore :

E(-2;-4)
F(2;2)

So here, we have :

x_{1} =-2
y_{1} =-4

x_{2} =2
y_{2} =2

Now, Let's apply the formula :

M((-2+2)/2 ; (-4+2)/2)
M(0;-1)

In short, the answer would be : B) (0;-1).

Hope this helps !

Can you guys help me solve this equation with step-by-step help, please...
Alex

Step-by-step explanation:

-2x - 5y = 16___(1)

2x - 3y = -16___(2)

(1) + (2) ==> -2x -5y = 16

(+) <u>2x -3y = -16</u>

-8y = 0

y = 0/-8

y = 0

y=0 in (1)

(1)---> -2x-5y =16

-2x - 5(0) = 16

-2x - 0 = 16

-2x = 16

x = 16/-2

x = -8

x = -8 , y = 0

-5x + 2y = 11__(1) ; -3x + 4y = -13___(2)

multiply eqn(1) with 2

2 × (1) : -10x + 4y = 22___(3)

(3) - (2) :. -10x + 4y = 22

(-) <u>-3x </u><u>+</u><u> </u><u>4</u><u>y</u><u> </u><u>=</u><u> </u><u>-</u><u>1</u><u>3</u>

-7x = 35

x = 35/-7

x = -5

x=-5 in (1)

(1) : -5x + 2y = 11

-5(-5) + 2y = 11

25 + 2y = 11

2y = 11 - 25

2y = -14

y = -14/2

y = -7

x = -5 , y = -7
