Answer:
D. -19/2
Step-by-step explanation:
Well, we know that R is greater than Y and that at the midpoint, R is 10.5, so Y can't be greater than this (c, 13) and that it isn't the same (b, 10.5). It could either be -8 or -19/2 (which is -9.5). Being that your first coordinate is in fraction form, the second one would also have the be, making the answer D. -19/2

Please check the explanation.
Step-by-step explanation:
Given the vector
v = 6i + 2√3j
The Magnitude of a vector:
![\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b}](https://tex.z-dn.net/?f=%5Cmathrm%7BApply%5C%3Aradical%5C%3Arule%7D%3A%5Cquad%20%5Csqrt%5Bn%5D%7Bab%7D%3D%5Csqrt%5Bn%5D%7Ba%7D%5Csqrt%5Bn%5D%7Bb%7D)
The Direction of a vector:
tan Ф = y/x
y=2√3
x = 6
tan Ф = y/x
= 2√3 / 6
= √3 / 3
Answer:
B
Step-by-step explanation:
4x-5y=2 ...(1)
10x-21y=10 ...(2)
(1)+2(2) gives
24x-47y=22

I think the answer is A.
It's probably wanting you to use pythagorean theorem.
