You need to solve for each value x and y. These two equations provide the intersection of both whereby
y=2x-4 and y=x-1
this gives us, by replacing y in the first equation with x-1 = 2x-4
subtract the left side x from the right side gives us -1 = x - 4
subtracting known values x = 3
verfy the results gives us 2(3) - 4 = y
2 = y
also 3 - 1 = y
2 = y
so you wind up with x = 3 and y = 2
<u>Answer</u>
double the length of DO
<u>Explanation</u>
For a trapezium, two of the opposites are parallel. The diagonals act like a transverse to the two the pair of parallel lines.
This makes the two diagonals to have some properties.
In the diagram shown, if 2AO = CO, for the other diagonal 2DO = BO.
∴ the length of BO is double the length of DO.
