Remark
You are using the midpoint formula. Instead of finding the midpoint, you are looking for one of the points, so you have to rearrange the formula a little bit.
Givens
Midpoint (4,2)
One endpoint (6,1)
Object
Find the other endpoint.
Formula
m(x,y) = (x1 + x2)/2, (y1 + y2)/2)
Solution
Find the x value
4 = (6 + x2)/2 Multiply both sides by 2
4*2 = 6 + x2 Subtract 6 from both sides.
8 - 6 = x2
x2 = 2
Find the y value
2 = (1 + y2)/2 Multiply by 2
4 = 1 + y2 Subtract 1 from both sides.
4 - 1 = y2
y2 = 3
Conclusion
R(x,y) = (2,3)
It looks like the scale is balanced so that means you can set one side equal to the other which leaves you with the equation x+(-10)=-16
To get x by itself add x to each side to get x=-6
X=-6 is your answer
Answer: A and B
Step-by-step explanation:
I think that the answer is A and B because in this case, R is clearly a negative number, because it’s below 0. So if we change the symbol in front of the R, it has to be positive. Let’s say R is -20. Negative R should be - - 20, which is + 20. So -R > 0. We and also say that -R = V because there are an equal number of bounds that separate R and V from 0, and since -R is the inverse of R, it has to be equal to V.
