The best way to do this question is to use elimination. Elimination is a way to find out the POINT OF INTERSECTION between two lines. Let me show you how.
3y+4x=3
x+3y=-6
Elimination is a way to remove any same variable with the same coefficient. In this case, there is 3y in both equations. In this case, we subtract to eliminate.
3y-3y+4x-x=3+6 It's plus 6 because two negatives become positive.
3x=9 Divide both sides by 3
x=3
Now you can find y.
x+3y=-6
3+3y=-6
3y=-9
y=-3
Therefore, the POI is (3,-3). I hope you understand this. Make sure to mark as brainliest.
It would be 103.33333333 ect. because you divide 310 by 3
Answer:
Transitive property of equality is not a justification for the proof.
Step-by-step explanation:
We draw a right angle ΔACB. CD is perpendicular to AB.
Let AC = a , BC = b , AB = c and CD = h
Now in ΔABC and ΔACD
∠C = ∠D and ∠A = ∠A
from AA similarity postulate
ΔABC similar to ΔACD.
Hence,
= 
= c × x ·····················(1)
Now in ΔABC and ΔCBD
∠C = ∠D and ∠B = ∠B
from AA similarity postulates
ΔABC similar to ΔCBD
Hence,
= c × y······················(2)
Add equation (1) and (2)
+ = cx + cy
+ = c(x+y)
+ = 
[because x+y=c]
Transitive property is not useful for this proof.

Answer:
y=10
Step-by-step explanation:
1.7y+37 is 14 less than the value of 9.3y–25
- 1.7y + 37 = 9.3y - 25 - 14
- 1.7y + 37 = 9.3y - 39
- 9.3y - 1.7y = 37 + 39
- 7.6y = 76
- y = 76/7.6
- y = 10
Answer is 10
