A.) it opens up because it is positive. B. The vertex is a minimum, because it opens up C/ The axis of symmetry is X=-1, the Vertex is (-1,-2). The Y interecept is y= -1
It would make a lot more sense if the choices were 's' instead of '8'. With that being said, the answer should have a value that is greater than -10. That would be a positive number, or a negative number from -1 to -9. <em>So, the acceptable answers would be A and B.</em>
Answer:
34
Step-by-step explanation:
Angle 6 + angle 7 = 90 degrees
angles 6 and 7 are complementary
I don't remember the names of the theorems at all, but we know that AD ≈ DE ≈ EB (Segment Addition). Which means <ACD ≈ <DCE ≈ <ECB (not completely sure how to prove this). Therefore, <1 ≈ <2. (Don't forget to state that <1 ≈ <ACD and <2 ≈ <ECB). With this and Angle Addition, we know that <ACE ≈ <DCB, so with SAS Congruence Theorem, we can prove ΔACE ≈ ΔBCD.
Hope that helps
The answer is 3
