Y= x-3 2y-2x=-6
1) add the 2x to both sides// 2y=2x-6
2) divide the 2 on both sides// y=x-3
Step-by-step explanation:
The Chord Intersection Theorem:
If 2 chords of a circle are AB and CD and they intersect at E, then
AE * EB = CE * ED.
Problem.
Two Chords AB and CD intersect at E. If AE = 2cm , EB = 4 and CE = 2.5 cm, find the length of ED.
By the above theorem : 2 * 4 = 2.5 * ED
ED = (2 * 4) / 2.5
= 3.2 cm.
is this what u wanted??????????
Substitute the y=1:
2x + 5(1) = 9
2x + 5 = 5
subtract the 5:
2x = 4
Divide by 2:
x = 2
