Final answer:
Since absolute values determine the distance between the number and the value whether the value is positive or negative. As distance is always positive.
Thus, |a| is always nonnegative, even though |a|=-a for negative values of a.
Step-by-step explanation:
Step 1
It is said that |a| is always nonnegative even though even though |a|=-a for negative values of a.
Step 2
This is because by the definition of an absolute value, any real number inside an absolute value symbol || will always be positive.
I think it’s 1.3, if it’s not than I’m so sorry
Answer: 30 miles per hour
Step-by-step explanation:
Speed = distance / time
= 300 / 10
= 30 miles per hour
Answer:
y(Cost)=.17x(x=miles)+4407
y=.17x+4407
Step-by-step explanation:
The cost of the vehicle is 4407$ fixed, with .17$ per mile. A liner equation, y=mx+b can be substituted with m being the cost per mile and 4407$ being the fixed annual value. Y is the total Cost of everything.
