Answer:
-3 = x
Step-by-step explanation:
4 (2x + 3) = 4x + 24 + 6x – 6
8x + 12 = 10x + 18
12 = 2x + 18
-6 = 2x
-3 = x
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
Stays the Same: 1,2,3,4
Goes Up: 5,6,7,8, etc...
1. The number 5 is located in the thousands place
2. Since the number 6 is located in the hundreds place, it's telling 5 to go up a number (turning 5 into a 6)
275,608 ⇒ 276,000
So the answer is 276,000
