Answer:
sry I just wanted the points I'm in middle school so I don't know this stuff either but can you give free brainlyest I'm soo close to my next rank I'd really appreciate it if you would
Midpoints are quite simple really the midpoint of (x2,y2) to (x1,y1) is just the average of the coordinates...
((x1+x2)/2, (y1+y2)/2) in this case you are only given one point and the midpoint and you really looking for the other endpoint so...
And we are only concerned with the x value so:
(x+9)/2=7
x+9=14
x=5
Answer: Symmetric Property
Step-by-step explanation: In this problem, notice that we're simply switching
the two sides of an equation and this idea is called the <em>symmetric property</em>.
The symmetric property allows us to switch the left and right
side of an equation which is why we can change n = -3 to -3 = n.
