HCF of 12 and 15 by Prime Factorization
1. As visible, 12 and 15 have only one common prime factor i.e. 3. Hence, the HCF of 12 and 15 is 3.
2. To find the HCF of 20 and 25, we will find the prime factorization of the given numbers, i.e. 20 = 2 × 2 × 5; 25 = 5 × 5. ⇒ Since 5 is the only common prime factor of 20 and 25. Hence, HCF (20, 25) = 5.
Answer:
Step-by-step explanation:
Given
(-2,-1) and (3,9).
Required
Determine the line equation
First, we calculate slope (m)
Where
So, we have:
The equation is then calculated using:
Open bracket
Subtract 1 from both sides
Answer:
96÷8=12 so it wold be $12 per CD AND 63÷6=10.5 there for making the CD $10.5 making Best Buy your answe
1.introduce a constant k hence
y=kx then find the value of the constant first -4=k2 hence k =-2
y=-2×-6
y=12
Step-by-step explanation:
follow the same procedure for the others and remember if it is inversely proportional then it becomes y=k/x
