On the left side, distribute the 2 to x and -3 so the left side should look like 5x+2x-6.
on the right, distribute the -2 to x and -1 so the right side should look like -2x+2.
combine like terms on the left to get 7x-6=-2x+2
add -2x from the right side to the left side to make the equation 9x-6=2 now it's a two step equation.
add 6 to 2 to get 9x=8. divide by 9 and x=8/9.
Answer:
5%
Step-by-step explanation:
fraction empty = empty / total
= 4/ (76+4)
= 4/80
=1/20
Changing to a percent
1/2 *5/5 = 5/100 = 5%
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
1/10 * n=90
n=90*10=900
1/10*900=90
I hope this helped. :)
