Answer:
A parallelograms are rectangles
Using <span>Descartes' rule of signs.
There are 4 changes of signs of coefficients:
+ to - (+x^6-x^5)
- to + (-x^4+4x^3)
+ to - (+4x^3-12x^2)
- to + (-12x^2+12)
Therefore, there are 4,2 or 0 positive roots </span><span><span>at most</span>. So it must be the third answer.

80MPH -30MPH=50MPH
50MPH=residential area
50MPH/2MPH every second=25
it takes him 25 seconds to slow down

Its - 3/2 if you need to know how I solved it, lemme know :)
Answer:
Since you didn't provide any choices, a possible equations would be h = (m - 10) / 5
Step-by-step Solution:
Since we know that the flat-rate 10 doesn't have anything to do with the hourly rate, we first subtract that. Then, we divide that number by 5 to get rid of it, so we're only left with h.
This process of removing things from the equation by reversing their methods can be applied all over math and is a strategy vary commonly used.
