¹/₂x + 25 = -100
<u> - 25 - 25</u>
2 · ¹/₂x = -125 · 2
x = -250
<u>
Check</u>
¹/₂x + 25 = -100
¹/₂(-250) + 25 = -100
-125 + 25 = -100
-100 = -100
Your answer is correct.
Answer:
This statement is true for any N vectorial space.
By definition u·v=|u|·|v|·cos(α), where α is the angle between u and v.
If -1≤cos(α)≤1, we can assume:
|u·v|=||u|·|v|·cos(α)|=|u|·|v|·|cos(α)|≤|u|·|v|
