(-a^2 + 1) - (a^2 - 3) + (5a^2 - 6a^2 - 6a + 7)
(-a^2 - a^2 + 5a^2 - 6a^2) - 6a + 1 + 3 + 7
(-2a^2 - a^2) - 6a + 4 + 7
-3a^2 - 6a + 11
The answer is true.
Point X lies on the line of intersection of planes S and R. This means that point X lies on both plane S and plane R at the same time.
You could also try and imagine the diagram without plane S and see that point X lies on plane R. Then you can imagine the same diagram without plane R and see that point X lies on plane S.
Let me know if you need any clarifications, thanks!

Answer: 30 should be negative
Step-by-step explanation:
when having an equation like that, you must multiply -5 by 3, which equals to -15, then multiply-5 by 6 which then equals to -30. The correct equation should be -5(3+6)= -15+-30= -45
I think this should be correct, hope this helps!
The x coordinates are 3 and -5. They add to 3+(-5) = -2
Cut this in half to get -2/2 = -1
The x coordinate of the midpoint is x = -1
-------------------
The y coordinates are 2 and 5. They add to 2+5 = 7.
Then we cut this in half to get 7/2 = 3.5
The y coordinate of the midpoint is y = 3.5
-------------------
Overall, the midpoint is (-1, 3.5)
<h3>Answer: (-1, 3.5) which is the same as (-1, 7/2)</h3>
