Answer:
Option C is correct.
Value of BE is 6 units
Step-by-step explanation:
Properties of the rectangle:
- Opposite side of the rectangle are same.
- Each angle of the rectangle is 90 degree
- Opposite angles of the rectangle are same.
- Diagonals of the rectangle are equal.
In rectangle ABCD:
Given that: AC = 12 units
Diagonals of ABCD are: AC and BD
By properties of rectangle:
BD = AC = 12 units.
We have to find the value of BE.
E is the point of intersection that divide the diagonal in equal parts.
BD = BE+ED
Since, ED = BE { by properties of rectangle}
then;
BD = 2BE
Substitute the given values we have
Divide both sides by 2 we get;
BE = 6 units.
Therefore, the value of BE is 6 units.

Answer:
(x, y) = (2, -2)
Step-by-step explanation:
We would normally choose to use substitution when x or y could be easily solved-for without having fractions involved. That is not the case here. However, we observe that the term 3y appears in both equations, so we can substitute for "3y" instead of "y".
From the second equation, ...
3y = 5x -16
Substituting into the first equation, ...
2x +(5x -16) = -2
7x = 14 . . . . . . . . . add 16
x = 2 . . . . . . . . . . divide by 7
Using our equation for y, we get ...
3y = 5(2) -16 = -6
y = -2 . . . . . . . . . divide by 3
The solution is (x, y) = (2, -2).
