Answer:
It should be a graph of two branches, one on the top right, and bottom left, and the center of them should be at (-2, 1).
Step-by-step explanation:
f(x)=(x^2-16)/(x^2-2x-8)
= (x+4)(x-4)/(x-4)(x+2)
=(x+4)/(x+2)
=((x+2)+2)/(x+2)
=1+2/(x+2)
So the center is at (-2, 1)
For 11. It’s yes because it’s constant and yearly and for 12. A rent is a proportional real life example because it’s constant and it doesn’t change for 9. It’s yes because it’s constant and doesn’t change for a while for 10. It’s no because it’s not a constant relationship

Length of x is 98.2 m
<u>Step-by-step explanation:</u>
Step 1:
Use the trigonometric ratio tan 27° to find the common side of both the right angled triangles.
tan 27° = opposite side/adjacent side = opposite side/9
∴ Opposite side = 9 tan 27° = 9 × - 3.27 = -29.46 m
Step 2:
Use this side and trigonometric ratio cosine to find the value of x.
cos 49° = adjacent side/x = -29.46/x
∴ x = -29.46/cos 49° = -29.46/0.30
= 98.2 m (negative value neglected)
That’s a good one Because what is the domain of the function Y equals 2X
