Answer:
Good Luck!
<u><em>5 stars</em></u>
Step-by-step explanation:
By conservation of momentum,
(110.0 kg) (1.5 ms⁻¹) + (170.0 kg) (-2.0 ms⁻¹) = (110.0 kg) (-2.75 ms⁻¹) + (170.0 kg) v
where v is the final velocity of the second car.
Solve for v :
-175 kg•ms⁻¹ = -302.5 kg•ms⁻¹ + (170.0 kg) v
127.5 kg•ms⁻¹ = (170.0 kg) v
v = (127.5 kg•ms⁻¹) / (170.0 kg) = 0.75 ms⁻¹
All you need to do here is know where and how to plug in the numbers. In each equation, you'll have an initial fee, and an hourly fee, so your equation will be
y = i + hx, where i = the initial fee, and h = the hourly fee
So, after plugging them in, here's what you get:
Doors Galore: y = 40 + 50x
G&H: y = 60 + 40x
Answer:
1/5? 0.2?
Step-by-step explanation:
Answer:
y-10 = -4(x + 3)
Step-by-step explanation:
The point slope formula is y-y₁=m(x-x₁). so, you fill in the values.
y-(10) = -4(x-(-3)). then you cancel the negative to end up with y-10 = -4(x + 3).
