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:
4 meters
Step-by-step explanation:
Given a quadratic equation in which the coefficient of is negative, the parabola opens up and has a maximum point. This maximum point occurs at the line of symmetry.
Since the divers height, y is modeled by the equation
Step 1: Determine the equation of symmetry
In the equation above, a=-1, b=2, c=3
Equation of symmetry,
Step 2: Find the value of y at the point of symmetry
That is, we substitute x obtained above into the y and solve.
The maximum height of the diver is therefore 4 meters.
