Find the Mid point of (-5,-9) (-7,-4)
lyudmila [28]

Answer: ( -6 , -6.5 )

Step-by-step explanation:

The formula for calculating Mid - point is given by

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

x_{1} = -5

x_{2} = -7

y_{1} = -9

y_{2} = -4

substituting into the formula , we have

M = \frac{-5-7}{2} , \frac{-9-4}{2}

M = \frac{-12}{2} , \frac{-13}{2}

Therefore : mid point = ( -6 , -6.5 )

Omg help me please like I just can't right now <br><br> 2x-6y= -12 <br> x+2y=14
steposvetlana [31]

here,

2x-6y= -12

2(x-3y)= -12

x-3y = -6...........eq1

x+2y=14............eq2

we can subtract the above two given equations

we get,

x - 3y =  - 6 \\ x + 2y = 14

___________

- 5y =  - 20

so,

y=4

now to find the value of x we have to substitute the value of y in any of the above two equations, I choose eq2

we get,

x + 2y = 14 \\ x + 2 \times 4 = 14 \\ x + 8 = 14 \\ x = 14 - 8 \\ x = 6

<h3>so,</h3><h3> x=6,y=4</h3>
