A. You divide 1 (infront of x) by 12 to get 12. You divide -6 by 12 to get -2 for the y intercept.
A is correct. Just move the negative sign from in front of the 9 and place it in front of the 4.
Answer:
3 : 10
Step-by-step explanation:
2 kg = 2000g
600g peanuts : 2000 cashew nuts
600 : 2000
divide both sides by a common divisor ( 200)
600/200 : 2000/200
3 : 10
Answer:
Option D doesn't make any sense.
Step-by-step explanation:
D) 7 hours of sleep correspond to an age of 19 years.
That is wrong.
If we use the expression provided
hours = 8 + 0.5*(18 -age)
hours = 8 + 0.5*(18 -19)
hours = 8 + 0.5*(-1)
hours = 7.5
