|-5x+10| is just 5x + 10 > 10
so 5x + 10 > 10
-10 -10
5x > 0
/5 /5
x > 0 is the answer to this Inequality
hope this helps ;-)
Answer:
Step-by-step explanation:
Given that ||v|| = 2 and ||w|| = 3, and the angle between v and w is 120 degrees
We know by definition of dot product and properties that
where t is the angle between them
Using this we find
(a) v·w =
(b) ∥2v+w∥
(c) ∥2v−3w∥
Let these there numbers be assigned to variables x, y and z. Since you want to find the sum, add all numbers. However, the sum has boundaries between 10 and 20. Therefore, you will have to use inequality symbols. The two addition equations that could be formulated are:
<em>x+y+z > 10</em>
<em>x+y+z < 20</em>
Exact form: log (972)
decimal form: 2.98766626...

Collect like terms
-3w - 7 w =5
Divide both sides by -10
-10w =5
w = -1/2
