Find the coordinate of the midpoint of the segment with the given endpoints -7 and 8
Pachacha [2.7K]

Answer:

<em>The coordinate of the midpoint is 1/2</em>

Step-by-step explanation:

<u>Midpoint</u>

The midpoint of a segment defined in a one-dimension system is

\displaystyle \bar x=\frac{x_1+x_2}{2}

Where x1 and x2 are the coordinates of the points.

The given segment has endpoints x1=-7 and x2=8, thus:

\displaystyle \bar x=\frac{-7+8}{2}

\displaystyle \bar x=\frac{1}{2}

The coordinate of the midpoint is 1/2

Solve the system of equations by elimination. Explain your reasoning or show your work.
saul85 [17]

9514 1404 393

Answer:

  (x, y) = (5, 4)

Step-by-step explanation:

Subtracting the second equation from the first eliminates the x term.

  (4x +6y) -(4x +2y) = (44) -(28)

  4y = 16 . . . . simplify

  y = 4

Using the second equation to find x, we have ...

  4x +2(4) = 28

  x + 2 = 7 . . . . . . divide by 4

  x = 5 . . . . . . . . . subtract 2

The solution is (x, y) = (5, 4).
