Answer:
y=-9x-9
Step-by-step explanation:
Just plug in your Ys and Xs in order to get y=-9x-9
The statement EF=2.GF (Option A) and the statement
(Option C) are true for the ΔEFG.
<h3>What are trigonometric ratios?</h3>
The six trigonometric ratios of a right-angle triangle are Sin, Cos, Tan, Cosec, Sec and Cot. Trigonometric ratios are used to measure the sides of the right triangle.
Given that in ΔEFG, m∠E=30°, m∠F=60° and m∠G=90°.
Wow, sin 30°![=\frac{GF}{EF}](https://tex.z-dn.net/?f=%3D%5Cfrac%7BGF%7D%7BEF%7D)
⇒![\frac{1}{2} =\frac{GF}{EF}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%3D%5Cfrac%7BGF%7D%7BEF%7D)
⇒EF=2.GF
and sin 60°![=\frac{GE}{EF}](https://tex.z-dn.net/?f=%3D%5Cfrac%7BGE%7D%7BEF%7D)
⇒![\frac{\sqrt{3} }{2} =\frac{GE}{EF}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B3%7D%20%7D%7B2%7D%20%3D%5Cfrac%7BGE%7D%7BEF%7D)
⇒![\frac{\sqrt{3} }{2} .EF=GE](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B3%7D%20%7D%7B2%7D%20.EF%3DGE)
Therefore, the statement EF=2.GF (Option A) and the statement
(Option C) are true for the ΔEFG.

Answer:
x = -4
Step-by-step explanation:
x+y = -10 or y = -10 - x
substitute this into the second equation
x - y = 2
x - (-10-x) = 2
2x + 10 = 2
2x = -8
x = - 4
