Find the coordinates of Rif M(-4, 5) is the midpoint
of RS and S has coordinates (0, -10).

R = (-8, 20)

Step-by-step explanation:

Given that :

M is the midpoint of RS

M = (-4, 5)

S = (0, - 10)

NOTE :

midpoint, M equals

Mx = (Rx + Sx) / 2

My = (Ry + Sy) / 2

Mx = - 4, Sx = 0, My = 5, Sy = - 10

Mx = (Rx + Sx) / 2

-4 = (Rx + 0) / 2

-8 = Rx + 0

Rx = - 8

My = (Ry + Sy) / 2

5 = (Ry + (-10)) / 2

10 = Ry - 10

10 + 10 = Ry

Ry = 20

Hence, coordinates of R = - 8 and 20

R = (-8, 20)

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
