explain how to solve it please
Answers
Answer:
x = -3
Step-by-step explanation:
Subtract 2 from both sides of the equation.
3x + 2 = 4x + 5
3x + 2 - 2 = 4x + 5 - 2
Step 2.
Simplify. Subtract the numbers 3x =4x + 3
Now subtract 4 from both sides.
Combine like terms -x = 3
Divide both sides of the equation.
Cancel terms that are in both the numerator and denominator
Divide the numbers
And that's how X = -3

Answer:
k = 0.2
A = (M / P₀) − 1
Step-by-step explanation:
dP/dt = kP
When t = 0, P = 1000 and dP/dt = 200.
200 = 1000k
k = 0.2
P = M / (1 + Ae⁻ᵏᵗ)
When t = 0, P = P₀.
P₀ = M / (1 + A)
1 + A = M / P₀
A = (M / P₀) − 1

IX+XC= WHAT IS THE ANSWER
Answers
Answer: X googled it
This converts to the number 99
=========================================================
Explanation:
The upper case letter i means the number 1 in roman numerals. The X represents 10. The C represents 100.
I = 1
X = 10
C = 100
When we form something like IX, we have the smaller digit first and then a larger digit next. Whenever this happens, we subtract
IX = 10-1 = 9
Similarly
XC = 100-10 = 90
So we can see that
IX + XC = 9 + 90 = 99
---------------------------
Since XC is larger than IX, we list XC first when it comes to adding
In other words, we need to write IX+XC as XC+IX which collapses to XCIX
Placing XC next to IX without a plus sign implies the plus sign is there. This is effectively how roman numerals work (they are additive)
So,
XCIX = XC+IX = 90+9 = 99
Note how the XC takes care of the tens digit while IX takes care of the units digit.

Alex's house (point F) lies on the same street as her school (point H). Alex's bus stop (point G) lies between her house and her school. Given FG=2x meters, GH=1,000 meters and FH=1,200 meters. What is the value of x in meters?
FG=2x meters, GH=1,000 meters and FH=1,200 meters.
FH = FG + GH
1200 = 2x + 1000
1200 - 1000 = 2x
200.= 2x
x.= 200/2
x = 100

In 2012, the population of a city was 5.82 million. The exponential growth rate was 2.95% per year.
a) Find the exponential growth function.
b) Estimate the population of the city in 2018.
c) When will the population of the city be million?
d) Find the doubling time.
Answers
Answer:
a) P(t) = 6.57e ^{0.0287t}P(t)=6.57e
0.0287t
b) P(6) = 7,805\ millionP(6)=7,805 million
c) t = 14.64\ yearst=14.64 years
d) t = 24.15\ yearst=24.15 years
Step-by-step explanation:
a) The function of exponential growth for a population has the following formula:
P(t) = p_0e ^{rt}P(t)=p
0
e
rt
In this equation:
p_0p
0
is the initial population
r is the growth rate
t is the time in years
In this problem we know that
r = 2.87\% = 0.0287r=2.87%=0.0287
p_0= 6.57p
0
=6.57 million in the year 2012.
So the equation is:
P(t) = 6.57e ^{0.0287t}P(t)=6.57e
0.0287t
Where t = 0t=0 represents the year 2012
b) If t = 0t=0 in 2012, then in 2018 t = 6t=6
The population in 2018 is:
\begin{gathered}P(t = 6) = 6.57e ^{0.0287(6)}\\\\P(6) = 7,805\ million\end{gathered}
P(t=6)=6.57e
0.0287(6)
P(6)=7,805 million
c) To know when the population is equal to 10 million we must equal P(t) to 10 and solve for t.
\begin{gathered}P(t) = 10 = 6.57e ^{0.0287t}\\\\\frac{10}{6.57} = e ^{0.0287t}\\\\ln(\frac{10}{6.57}) = 0.0287t\\\\t = \frac{ln(\frac{10}{6.57})}{0.0287}\end{gathered}
P(t)=10=6.57e
0.0287t
6.57

ln(

)=0.0287t
t=
0.0287
ln(

)
t = 14.64\ yearst=14.64 years
d) The function is doubled when P(t) = 2p_0P(t)=2p
0
P(t) = 2(6.57) = 13.14 = 6.57e ^{0.0287t}P(t)=2(6.57)=13.14=6.57e
0.0287t
We solve for t.
\begin{gathered}\frac{13.14}{6.57} = e ^{0.0287t}\\\\ln(\frac{13.14}{6.57}) = 0.0287t\\\\t = ln{13.14}{6.57})}{0.0287})\
end
{gathered}
