I think it’s A “ f(x) = -3x + 12” because your going down so it’s a negative
Solved:
A -3x/ +3 12 +3 means x=15
Now B is 3x/ -3 15 -3 means x = 12
I don’t think C is the answer at all I think it’s A but I’m not 100% sure
XD I hope my answer helps you one way or another
Yes! It can simplified to 2/5 or in decimal form it would be 0.4 . Hope this helps!

Answer:
The triangle is not acute because 2² + 4² < 5²
Step-by-step explanation:
The square of the hypotenuse of a right triangle with the given short sides would be 2² +4² = 20. So, that hypotenuse would be √20, about 4.47. The long side of this triangle is longer than that, so the angle opposite is larger than 90°. The triangle with sides 2, 4, 5 is an obtuse triangle.
The triangle is not acute because 2² + 4² < 5²
