Answer:
r= 3 h = 6 then use 3^2 + 6^2 = l^2
Step-by-step explanation:
<span>38 - 7r = 3(6 - 4r)
38 - 7r = 18 - 12r
-7r + 12r = 18 - 38
5r = -20
r = -4</span>
The train is going 60 mph and the train is going 45 mph
You would need to get y be itself to make an equation so you would first subtract 1 from both sides--
Py = Qx - 1
Then you would need to divide both sides by P to have y by itself--
y = Qx-1/P
