Answer:
Step-by-step explanation:
<u>Given system</u>
- 4x + 6y = 18
- (y + 2) = 1/3(x + 2)
<u>Solution is the intersection point:</u>
<u>Simplify the first equation:</u>
- 2x + 3y = 9
- 3y = -2x + 9
- y = -2/3x + 3
<u>Check:</u>
- 1/9 = -2/3*4 1/3 + 9
- 1/9 = -26/9 + 9
- 1/9 = (27 - 26)/9
- 1/9 = 1/9
<u>Simplify the second equation:</u>
- y + 2 = 1/3x + 2/3
- y = 1/3x + 2/3 - 2
- y = 1/3x - 4/3
<u>Check</u>:
- 1/9 = 1/3*13/3 - 4/3
- 1/9 = (13 - 12)/9
- 1/9 = 1/9

Step-by-step explanation:
Answer:
The correct answer is C (ABE = DBC)
Step-by-step explanation:
This is because opposite angles are congruent to each other.
