answer is B, because it comes -50/49
(7,4) they’re both positive numbers
Answer:
This route is 112 miles long.
Step-by-step explanation:
Let's say that the passeneger meant to get off at Station A but instead got off at Station B. We are told that the distance from Boston to Station A is 1/3 of the train's total route. Let's say that the train's total route is x miles long. Now we can say that the distance from Boston to Station A is 1/3x.
We are told that the distance from Station A to Station B is 14 miles.
We are also told that the distance from Station B to the end of the route is 13/24 of the whole route. Since we already decided that the whole route is x miles long, we can say that the distance from Station B to the end route is 13/24x.
Add up all of these distances to get the total distance of the trains route:
13/24x+14+1/3x=x.
14+13/24x+8/24x=x
14+21/24x=x
14=3/24x
14=1/8x
112=x
Hope this helps!
X² + 8x + 3 < 0
use the quadratic formula;
x = -8 + 2√13 / 2, -8 - 2√13 / 2
-4 - √13 < x < -4 + √13 (this is what they're asking as in interval notation)
hope this helps, God bless!
I think it would be 4 because all the other answers don't make sense
