Answer:
y = x - 8
Step-by-step explanation:
In order to solve this, we need to use point-slope form.:
y - y1 = m(x - x1)
Substitute the numbers into the equation:
y - (-8) = 1(x - 0)
y + 8 = x
y = x - 8

2cm
Step-by-step explanation:
It depends on your fuel economy, how much fuel the car burns per 100 miles etc.
Answer:
The average speed is:
![\var{v}=75\: miles/h](https://tex.z-dn.net/?f=%5Cvar%7Bv%7D%3D75%5C%3A%20miles%2Fh)
Step-by-step explanation:
The average speed equation is given by:
![\var{v}=\frac{\Delta x}{\Delta t}](https://tex.z-dn.net/?f=%5Cvar%7Bv%7D%3D%5Cfrac%7B%5CDelta%20x%7D%7B%5CDelta%20t%7D)
Were:
- Δx is the displacement (225 miles)
- Δt is the change in time (3 hours)
Then we have:
![\var{v}=\frac{225}{3}](https://tex.z-dn.net/?f=%5Cvar%7Bv%7D%3D%5Cfrac%7B225%7D%7B3%7D)
![\var{v}=75\: miles/h](https://tex.z-dn.net/?f=%5Cvar%7Bv%7D%3D75%5C%3A%20miles%2Fh)
I hope it helps you!
Answer:
(g-f)(3) = 20
Step-by-step explanation:
g(3)=6 * (3) = 18
f(3)= 4-2(3) = 4 - 6 = -2
So
(g-f)(3) = 18 - (-2) = 20
