Answer: Addition property of equality
Step-by-step explanation:
Assuming you meant 3x-9=2x+5, it would be the addition property of equality since you are adding 9 to both sides.
We know that
<span>Joey and Rita paint a room in 8 hours
so
100%----------> 8 hours
X%----------> 1 hour
x=100/8-----> 12.5%
that means
</span>Joey and Rita paint 12.5% of a room in 1 hour
Billy paint a room in 12 hours
so
100%----------> 12 hours
X %------------> 1 hour
x=100/12----> x=8.33 %
that means
Billy paint 8.33% of a room in 1 hour
i<span>f all three work together
then
All three paint (12.5%+8.33%) in 1 hour
20.83%------------> 1 hour
100%------------> x
x=100/20.83-----> x=4.8 hours
the answer is
4.8 hours</span>
Answer:
?
Step-by-step explanation:
One obvious asymtote is where x makes f(x) infinite. we know log(0) is infinite so x-16=0 or x=16.
