Answer:
C. Time since the person starts walking is the input.
D. t represents the input.
Step-by-step explanation:
The distance a person walks, d, in kilometers, is a function of time, t, in minutes, since the walk begins.
So, we can write d = f(t)
If the person is moving with constant speed, then the above function will be linear.
Now the true statements are
C. Time since the person starts walking is the input.
D. t represents the input.
All the other statements are false. (Answer)
Step-by-step explanation:

Answer:

Step-by-step explanation:
Given equation of line:

To find the equation of line perpendicular to the line of the given equation and passes through point (8,2).
Applying slope relationship between perpendicular lines.

where
and
are slopes of perpendicular lines.
For the given equation in the form
the slope
can be found by comparing
with standard form.
∴ 
Thus slope of line perpendicular to this line
would be given as:

∴ 
The line passes through point (8,2)
Using point slope form:

Where
and 
So,

Using distribution.


Adding 2 to both sides.


Thus the equation of line in standard form is given by:

Answer:
x = - 6
Step-by-step explanation:
Given
= 3
Multiply both sides by 5 to clear the fraction
9 - x = 15 ( subtract 9 from both sides )
- x = 6 ( multiply both sides by - 1 )
x = - 6
