The Prove that two non-zero vectors are collinear if and only if one vector is a scalar multiple of the other is given below.
<h3>What are the proves?</h3>
1. To know collinear vectors:
∧ ⁻a ║ ⁻a
If ⁻b = ∧ ⁻a
then |⁻b| = |∧ ⁻a|
So one can say that line ⁻b and ⁻a are collinear.
2. If ⁻a and ⁻b are collinear
Assuming |b| length is 'μ' times of |⁻a |
Then | 'μ' ⁻a| = | 'μ' ⁻a|
So ⁻b = 'μ' ⁻a

The answer is B, all real number
Answer:
x = -
Step-by-step explanation:
-
x - 1 = 
add 1 to both sides:
-
x = 
multiply both sides by 4:
-3x = 
divide both sides by -3:
x = -
3/4 * h = 2 1/4
3/4* h * 4/3 = 9/4 * 4/3
h = 3
Answer:
Jack earned $2560 this summer.
Step-by-step explanation:
Given:
Money given away = $256
Percentile of money give away = 10%
We need to find the total money he earned this summer.
Solution:
Let the total money he earned this summer be 'x'.
So we can say that;
Money given away is equal to Percentile of money give away multiplied by total money he earned this summer and then divided by 100.
framing in equation form we get;

Now multiplying both side by 10 we get;

Hence Jack earned $2560 this summer.
