Answer:
The pool is being filled
Step-by-step explanation:
The function definition tells you ...
f(5) = the volume of water in the pool 5 minutes after they start
f(10) = the volume of water in the pool 10 minutes after they start
So, the inequality ...
f(5) < f(10)
means the volume of water in the pool 10 minutes after they start is greater than it is 5 minutes after they start. In short, <em>they are filling the pool</em>.
You cant factor by 9 because 15 cant be factored by 9. you can factor it by 5 and get 18x - 3 might want to check my answer
Answer: i would say no there not always negative
Use the distance formula <em>or Pythagorean Theorem</em> to find the length of each of the sides.
<u>(-5, -4) to (2, 6)</u>
d =
=
=
=
<u>(2, 6) to (4, -4)</u>
d =
=
=
=
= 2
<u>(-5, -4) to (4, -4)</u>
you can just count the distance between the coordinates: d = 9
<u>Perimeter</u> = (-5, -4) to (2, 6) + (2, 6) to (4, -4) + (-5, -4) to (4, -4)
= + 2 + 9
Answer: + + 9
