The slope and speed of Plane A is 375mph and slope and speed for Plane B is 425 mph... so Plane A travels the fastest
13 units.
Since both are negative, and they’re just asking for distance between, you can just subtract 12 from 25 to get 13.
This is how I would do it:
-8x=28-4y divide the entire equation by 4
-2x=7-y Put y back on the left and put x on the right
y=7-2x.
D=ab-c Theres your answer
a-1<span />
