1 hour has 60 minutes.
Divide miles per hour by 60 to get miles per minute:
200 / 60 = 3.33 ( 3 1/3 ) miles per minute.
The value of
is 4.
By Geometry, we know that line segment
, which is equivalent to:
![DF = 3\cdot x + 2 + x + 5](https://tex.z-dn.net/?f=DF%20%3D%203%5Ccdot%20x%20%2B%202%20%2B%20x%20%2B%205)
(1)
Now we solve algebraically the resulting expression.
If we know that
, then we solve the equation for
:
![4\cdot x + 7 = 23](https://tex.z-dn.net/?f=4%5Ccdot%20x%20%2B%207%20%3D%2023)
![4\cdot x = 16](https://tex.z-dn.net/?f=4%5Ccdot%20x%20%3D%2016)
![x = 4](https://tex.z-dn.net/?f=x%20%3D%204)
The value of
is 4.

When x is equal to -1:
f(-1)=6(-1)-3
=-7-3
=-10
y=-10
When x is equal to 0:
f(0)=6(0)-3
=0-3
=-3
y=-3
When x is equal to 1:
f(1)=6(1)-3
=6-3
=3
y=3
When x is equal to 2:
f(2)=6(2)-3
=12-3
=9
y=9
