Point a is at (-6, 8) and point M is at (0, 0.5). Point M is the midpoint of point A and point B what are the coordinates of poi
Travka [436]

The coordinates of point B is (6, -7), if the Point A is at (-6, 8) and point M is at (0, 0.5).

Step-by-step explanation:

The given is,

                A (-6, 8)

                M (0, 0.5)

                Where, A is first point

                             M is mid point

Step:1

          Formula for calculation of Mid point between two points,

                        (x,y)= (\frac{x_{1}+x_{2}  }{2} , \frac{y_{1}+y_{2}  }{2} )........................(1)

          Where,

                   A (-6, 8) - ( x_{1},y_{1}  )

                   M ( 0, 0.5) - (x,y)

           Substitute the values,

                     ( 0, 0.5) = (\frac{-6+x_{2} }{2}, \frac{8+y_{2} }{2})

           For x value,

                   0 = \frac{-6+x_{2} }{2}

                   0 = -6 + x_{2}

                  x_{2} = 6

          For y values,

                  0.5 =  \frac{8+y_{2} }{2}

                     1 = 8 + y_{2}

                      y_{2} = -7

Result:

          The coordinates of point B is (6, -7), if the Point A is at (-6, 8) and point M is at (0, 0.5).

Select all of the expressions that are equivalent to 3x + 18
Assoli18 [71]

Answer:

3(x + 6) and 4x + 18 - x

Step-by-step explanation:

Let's solve each option to see whether we would get 3x + 18:

✔️2x + 9 + 2x + 9

Add like terms

2x + 2x + 9 + 9

4x + 18

✔️3(x + 6)

3*x + 3*6

3x + 18 (it is an equivalent)

✔️4x + 18 - x

Add like terms

4x - x + 18

3x + 18 (it is an equivalent)

✔️2(4x + 9)

8x + 18

Therefore, the expressions 3(x + 6) and 4x + 18 - x are equivalent to 3x + 18
