Answer:
-12
Step-by-step explanation:
Take the inverse function, and modulate it:

By taking x = 0, we can see that the y-intercept is clearly -12:

Therefore, the y-intercept is -12.
Answer:
I'm pretty sure It's D correct me if I'm wrong though. :)
Step-by-step explanation:
Answer:
angle B'CA'= angle BCA..... (common angle)
angle B'A'C = angle BAC.....(corresponding angels)
therefore,
ΔCB'A' ~ ΔCBA. ......(by A-A test of similarity)
therefore,
B'A'/ BA. = CA'/ CA....(congruent sides of congruent triangles)
now, B'A' = 5, CA'= 6 , CA = 6 + 3 = 9
5 / BA. = 6 / 9
therefore, 5 / BA. = 2 / 3

Answer : AB = 7.5 units
Answer:
<h2>C. </h2>
Step-by-step explanation:
We have the parabolas:
(1) y = x² + 2 and (2) y = x² - 6
The common shaded region is below parabola (1) and above parabola (2).
Therefore y < x² + 2 and y > x² - 6
Answer:
<5=120
Step-by-step explanation:
vertical angle theorem : so <3=<5
120=<5
