Answer:
D. 150 metres
Step-by-step explanation:
speed = (60) times 5/18 = 50/3
lenght of the train = (speed x time)
lenght = 50/3 times (9)
= 150 m.
Answer:
The slope of the line segment is
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
we have the points
(2,-5) and (-1, -1)
substitute in the formula
Answer:
The solution is the point (6,-1)
Step-by-step explanation:
<u><em>The correct question is</em></u>
Solve the system of equations and choose the correct ordered pair. 2x+6y=6 and 3x-2y=20
we have
----> equation A
---> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The intersection point both lines is (6,-1)
see the attached figure
therefore
The solution is the point (6,-1)
