2х + Зу = 9

Mathematics
1 answer:
umka2103 [35]3 years ago
5 0

Answer:

3

Step-by-step explanation:

Given the 2 equations

2x + 3y = 9 → (1)

- 2x + 2y = 6 → (2)

Adding the 2 equations term by term will eliminate x

(2x - 2x) + (3y + 2y) = (9 + 6), that is

5y = 15 ( divide both sides by 5 )

y = 3

When finding out if 2 triangles are congruent, is it possible to only use a side and angle if those are the only 2 provided? Hel
PIT_PIT [208]
Short answer: No and yes. 
Yes First.
If the lower right point (looks like an C perhaps or an F) and the middle point and the upper left point lie on the same line and if D the middle point and the upper right point lie n the the same line, then yes. You have angle side angle. The lower right angle is given as equal to the upper left angle. The angles at C are vertically opposite angles and they are equal and you have been given 2 enclosed sides that are equal.

No
If the points I've described are not on the same line, then the triangles are not congruent. If I can, I'll edit this a second time. 

Please Note:
You have done something that looks a bit illegal to me. I wouldn't just trade pictures. It only costs you another 5 points to issue another question. I do think, however, that it is very clever. In answering about 1700 questions, I've never seen this done. That's commendable.
