Set both angles equal to each other because they are vertical angles.
3x-3 = 2x + 13
3x-2x=13+3
1x =16
x=16

Answer:
-4,-3,-2,-1,1
Step-by-step explanation:
these numbers can be expressed in a fraction
Y = kx
k = y/x = 15/3 = 5
<span>when y = 4
5 = 4/x
x = 4/5
answer
</span><span>when y = 4 , x = 4/5</span>
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
