Question

1 MEDAL AND FAN QUESTION!!!!!!!!!!!!!!!!!!!!
1. M(4, 2) is the midpoint of RS The coordinates of S are (6, 1). What are the coordinates of R?

(2, 3)
(5, 1.5)
(8, 0)
(1.5, 3)
2.Look at the following number sequence.

9, 15, 21, 27, . . .

Based on the pattern, what are the next two terms?

39, 45
162, 972
33, 972
33, 39

Answer 1

The midpoint of a segment with enpoints

\( (x_1, y_1)\) and \( (x_2, y_2) \)

is \( (x_m, y_m) = ( \dfrac{x_1 + x_2}{2}, \dfrac{y_1 + y_2}{2} ) \)

You have \(x_m\) and \(x_1\). Solve for \(x_2\).

You have \(y_m\) and \(y_1\). Solve for \(y_2\).

Answer 2

ok so whats the answer

Answer 3

is it 3,1.5

Answer 4

Solve these two equations:

\(4 = \dfrac{6 + x_2}{2} \)

\(2 = \dfrac{1 + y_2}{2} \)

Answer 5

For 2., look at the difference between a number and the previous number.

Answer 6

i just want an answer

Answer 7

i got 3,1.5

Answer 8

That's not how OS works. We help each other solve problems, not just giving out answers. I can tell you your answer to 1. is not correct.

Answer 9

1. (2,3)
