Directrix is x =1, so it is horizontal parabola.Vertex is between the focus and directrix on equal distance 5-x=x-1, 2x=6,
x=3. y -coordinate of the vertex for this parabola equals y-coordinate of the focus.
Vertex (3,2).
Focus has x=5 >1, so it is directed to the right.
So monkeys/3=lions or monkeys=3(lions)
monkeys+lions=24
subsitute monkeys=3(lions) for monkeys in the second equation
3(lions)+lions=24
add like terms
4lions=24
divide both sides by 4
lions=6
subsitute lions=6 into second equation
monkeys+6=24
subtract 6 from both sides
monkeys=18
Since she donates 25%, take 25% and multiply it by 1,200
or,
Answer:
y=-6 that would be it. remember slope is rise over run
