First off, let's see this equation
so, notice, since it's already in slope-intercept form, we know the slope is just 2.
a line that is perpendicular to it, will have a negative reciprocal slope to it, let's check.
so, what is the equation of a line whose slope is -1/2 and goes through -1,2?
Answer:
1440 $
Step-by-step explanation:
3000 - 100%
x - 12%
360 - 1 years
(a)
If by "age in years" you mean that you only consider whole years, then this is not a one-to-one function, because you will have the same output for 365 inputs:
- If you're 0 to 364 days old, your age in years is 0
- If you're 365 to 729 days old, your age in years is 1
- ....
So, you can see that it is not true that every different input yields a different output.
(b)
This is a one-to-one function: since one mile is 1.609 kilometers, you can convert miles per hour into kilometers per hour by multiplying by 1.609:
x mph = 1.609x km/h
The inverse function would be
x km/h = x/1.609 mph.
