That's a line:
g(x)=0.5*x-1, pick up some x, and get the y.
For instace: x=0, g(0)=y=-1, x=2, g(2)=y=0.
Two pints are enough for a line.
Answer: the answer should be B
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:
8/10 = x-1 / x+2
4/5 = x-1 / x+2
4(x+2) = 5(x-1)
4x + 8 = 5x -5
13 = x
there you go :)
