D. congruent by CPCTC
E. congruent by SAS
F. not necessarily true
Answer: A, B, D, E
Okay uh
x = 2y + 9
14x + 2y = - 54
14x + 2y = - 54
14(2y + 9) + 2y = - 54
28y + 126 + 2y = -54
30y + 126 = -54
- 126 -126
30y = -180
30y/30 = -180/30
y = -6
x = 2y + 9
x = 2(-6) + 9
x = -12 + 9
x = -3
(x, y) = (-3, -6)
Answers:
6. Is 21
7. Is 10
8. Is 3 x 1
9. Is maybe 1 x 10
And sorry I don’t know 10
Answer:
We can now prove Euler's formula (v − e + f = 2) works in general, for any connected simple planar graph. Proof: by induction on the number of edges in the graph. Base: If e = 0, the graph consists of a single vertex with a single region surrounding it. So we have 1 − 0 + 1 = 2 which is clearly right.
Answer:50%
Step-by-step explanation: The correct way to calculate what percentage more attended the play is to first subtract the expected number from the actual number. 15 - 10 = 5 more attended than was expected. Next, you need to divide the 5 additional people by the 10 that were originally expected. 5 divided by 10 = 50%
