Answer:
The coordinate of point B is (4, 8.25)
Step-by-step explanation:
Here, we want to find the coordinates of point B
To do this, we are to use the section internal division formula as follows;
(x,y) = (nx1 + mx2)/(m + n) , (ny1 + my2)/(m + n)
In this case;
(x1,y1) = (2,6)
(x2,y2) = (5,9)
(m,n) = (3,1)
Substituting these values into the section formula, we have;
(x,y) = (1(1) + 3(5))/(1 + 3) , (1(6) + 3(9))/3 + 1)
(x,y) = (16/4, 33/4)
(x,y) = (4,8.25)
Answer:
The ordered pair is not a solution as both sides of the equation do not equal each other.
Step-by-step explanation:
(3,2); x + 6y = 13
(3) + 6(2) = 13
3 + 12 = 13
15 = 13
Answer: A
Step-by-step explanation:
Answer:
<em>Sali's speed was 18.75 km/h.</em>
Step-by-step explanation:
Jane took 3.5 hours to cycle the 63 km.
As, 
, so the speed of Jane will be: 
Suppose, the speed of Sali is 
km/h
Sali caught up with Jane when they had both cycled 30 km.
So, <u>the time required for Jane to cycle 30 km</u> 
and <u>the time required for Sali to cycle 30 km</u> 
Given that, Sali started to cycle 4 minutes or 
after Jane started to cycle. So, the equation will be.......
Thus, the speed of Sali was 18.75 km/h.
Not sure if there is a question here. However, I'll assume you're looking for when it lands. It takes about 24.6 minutes to land.
