The answer is x=-3
5-x=11+x
-11 -11 First subtract 11
-6-x=x
+x +x Now add x to both sides
-6=2x
~2 ~2 Finally divide by 2
-3=x Your answer is x=-3
The answer is false. This is because<u> 8 does not equal the number 28</u>.
Explination:
|8|
=
28
8≠28
Point form: (-2,-3)
Equation form: x=-2, y=-3
Answer:
n = 3/7
Step-by-step explanation:
Cos(2 arctan(4/3)) = cos(2 arccos(3/5)) = cos^2(arccos(3/5)) - sin^2(arccos(3/5)) = cos^2(arccos(3/5)) - sin^2(arcsin(4/5)) = (3/5)^2 - (4/5)^2 = 9/25 - 16/25 = -7/25.
