(x-5,y+8)
the x basically decreased- to the left
and y increased- upwards
Answer:
2007
Step-by-step explanation:
we have

This is a vertical parabola open upward
The vertex represent a minimum
p(x) is the population in thousands for a species of fish
x is the number of years since 1997
Remember that p(x) is in thousands
so
If the population reach 66,530 fish
then
the value of p(x) is equal to
p(x)=66.53
substitute in the quadratic equation



Solve the quadratic equation by graphing
The solution is x=10 years
see the attached figure
therefore
Find the year
Adds 10 years to 1997
1997+10=2007
Advanced rule of parallelograms
It takes only 2 years
because
31,006,000 x 1.2% = 6,201,200
so,
31, 006, 000 + 6,201,200 = 37, 207, 200
37, 207, 200 + 6,201,200 = 43, 408, 400
One pack = 14 ounces.
She has 8 packs.
If one candle takes up 7 ounces, then each pack can create 2 candles.
2 x 8 = 16. In total, she can make 18 candles.
