Answer:
If point C represents -1, then each space is 1 unit.
So, A = -10
B = -4
D=2
E=9
Let me know if this helps!
Answer:
17.3 in
Step-by-step explanation:
The distance, s = 40t₁ where t₁ is the time to complete the outward journey.
The same distance = vt₂ where t₂ is the time to complete the return journey at speed v.
For the whole journey, 2s=60(t₁+t₂). Therefore s=30(t₁+t₂)=40t₁=vt₂.
30t₁+30t₂=40t₁, 10t₁=30t₂, t₁=3t₂, so s=120t₂=vt₂ and v=120kph.
The speed is 99 kilometers. U welcome
Answer:
-0.25
Step-by-step explanation:
Coordinates of C = 
Coordinates of D = 
Let Coordinates of A= (x,y)
Since A point is located 1/4 the distance from C to D
So the remaining distance from point A to D is 3/4
Thus the ratio of CA : AD = m:n=1:3
Now to find points of A we will use section formula i.e.


Substituting the values:



Thus Find the x value for the point that is 1 over 4 the distance from point C to point D is -0.25
Hence option a is correct
