Answer:45 * t = 2.5 * (1-t)...the equation will have one solution.
Step-by-step explanation:
For this case, the first thing you should know is:
d: v * t
Where,
d: distance
v: speed
t: time
To go to school by bus we have:
d = 45 * t
To return from school we have:
d = 2.5 * (1-t)
how the distance is the same:45 * t = 2.5 * (1-t)
Answer:
The solution is in the image
It would be the first one (x,-y) because say for example you take the point of v1 (4,-1) and reflect across x axis you get (4,1) for v
You can tell if the equation is linear or not if the equation makes a straight line on a graph.
Answer:
1
Step-by-step explanation:
JK and KN is perpendicular.
Thus no planes contained them except 1
Which is a rectangle.
I hope this helps you :)
