What is the solution to the system of equations ? 2x-y=7 y=2x+3

1 answer:

8 0

<span>y = 2x + 3

</span><span>2x - y = 7

Substituting the value of y,

2x - (2x + 3) = 7

2x - 2x - 3 = 7

-3 </span>≠ 7

Hence, there is no solution to this equation. This equation does not even exist.

A line segment on a number line has its endpoints at -9 and 6. Find the coordinate of the midpoint of the segment.. . A. 1.5. *

Lyrx [107]

By definition, the midpoint is given by:
$m = (\frac{x1+x2}{2}, \frac{y1+y2}{2})$

Part A:
For the line segment we have:
$m = \frac{-9+6}{2}$
$m= \frac{-3}{2}$
$m = -1.5$
Answer:
the coordinate of the midpoint of the segment is:
B. -1.5

Part B:
For line segment HX we have:
$m = (\frac{-1+7}{2}, \frac{3-1}{2})$
$m = (\frac{6}{2}, \frac{2}{2})$
$m = (3,1)$
Answer:
the coordinates of the midpoint of the segment is:
A. (3,1)
