Answer:
<em>( -4 , 3 )</em>
Step-by-step explanation:
<em>Knowing that "y" is the line going up and down and "x' is the line going left to right.</em>
<em>Quadrant | = ( + , + )</em>
<em>Quadrant || = ( - , +)</em>
<em>Quadrant ||| = (- , - )</em>
<em>Quadrant |v = ( + , - )</em>
<u><em>Refer to image below if needed.</em></u>
<em>Hence, from the given we can conclude the following:</em>
<em>Quadrant || = ( - , +)</em>
<em>( x , y )</em>
<em>x = -4</em>
<em>y = 3</em>
<em />
<em>Thus, we have:</em>
<em>( -4 , 3 )</em>
<em />
<em>Therefore, the correct answer is ( -4 , 3 )</em>

Answer:
is NOT true.
Step-by-step explanation:
1.
......True
( 1 )² = 1
2.
If
........ NOT True
∴ x =± 1 .........this is correct
3.
......True
( -1 )² = 1
4.
x2 = 1 if and only if x = 1 or x = -1.
.........True
( 1 )² = 1
( -1 )² = 1
I assume you mean, that an angle and two sides are known.
A formula that can be used for irregular triangles is the cosine rule.

'b' and 'c' must be sides that are beside the angle 'A' (angle opposite 'a').
= 2x + 11
Steps
(8x+9) -(6x-2)
Remove ( a ) = a
8x + 9 - 6x + 2
Simplify
8x+ 9 - 6x + 2: 2x + 11
= 2x + 11 <----- your answer
Please tell me if this was right
