Answer:
8 crabs and 2 octopi
Step-by-step explanation:
Let c represent the amount of crabs and o represent the amount of octopi.
We can use this to set up a system of equations:
6c+8o=64
c=4o
We can solve this system using substitution. In this case, we can substitute 4o for c:
6(4o)+8o=64
24o+8o=64
Combine like terms
32o=64
Divide both sides by 32
o=2
Substitute 2 for o to solve for c:
c=4o=4(2)=8
There are 8 crabs and 2 octopi

Answer:
f(-4) = -2
Step-by-step explanation:
To find f(-4) use the "piece" of the function rule defined for x < -3 (because -4 is less than -3). That part of the rule says the output (range) value is x + 2, so f(-4) = -4 + 2 = -2.
