The coordinates of B are .
Solution:
Given A(2, –1), B(x, y) and C(4, 2)
AB is a line segment C is a point on AB.
AC : CB = 3 : 1
To find the coordinates of B:
Section formula:
The point divides the line segment and in the ratio
m : n are
Here, and m = 3, n = 1
Using section formula,
Substitute the given values in the section formula.
Equate the x-coordinates and y-coordinates.
Hence the coordinates of B are .
Answer:
-1 and -5
Step-by-step explanation:
You must account for negative u values (which the abs nullifies).
So and is what we have to solve for.
As for usual equations, isolate the u variable.
5u + 15 = 10
5u + 15 (-15) = 10 (-15)
5u = -5
u = -1
Now you can do the same operation for the other equation and you should get u = -5.
Let's make sure we did it right by replacing u with one of our solutions (-1 or -5).
That's true. What about the other one?
