Answer:

6(3x + 1/2)

9(2x + 1/3)

2(9x + 5) - 7

Step-by-step explanation:

6(3x + 1/2)= 18x + 3 ✅

9(2x + 1/3)= 18x + 3 ✅

4(4x + 1) -1= 16x + 3

2(9x + 5) - 7= 18x + 3 ✅

3(6x + 2) + 3= 18x + 9

lubasha [3.4K]
-21x^3 - 8x^3 = -29x^3
-7/4x^(1/2) - 0 = -7/4x^(1/2)
-6x^(1/4)
-12x^(-1/2)
12x^(-1/4)
14x^4

Therefore, the correct option is the 2nd one.

What does b represent in the equation of a line in the form y = mx + b?
Dvinal [7]
B is called "the vertical intercept" and is the value of y when x = 0.  Something like an initial value!

The population for Gulch Dry has been declining according to the function P(t)= 8000. 2^-t/29 where t is the number of years sin
Iteru [2.4K]
A)

\bf 1990-1910=80\leftarrow t
\\\\\\
P(t)=8000(2)^{-\frac{t}{29}}\implies P(80)=8000(2)^{-\frac{80}{29}}
\\\\\\
P(80)=8000\cdot \cfrac{1}{2^{\frac{80}{29}}}\implies P(80)=\cfrac{8000}{\sqrt[29]{2^{80}}}

and surely you know how much  that is.

b)

\bf P(t)=125\\\\\\  125=8000(2)^{-\frac{t}{29}}\implies \cfrac{125}{8000}=2^{-\frac{t}{29}}\implies \cfrac{1}{64}=2^{-\frac{t}{29}}
\\\\\\
\textit{now we take log to both sides}
\\\\\\
log\left( \frac{1}{64} \right)=log\left( 2^{-\frac{t}{29}} \right)\implies log\left( \frac{1}{64} \right)=-\frac{t}{29}log\left( 2 \right)
\\\\\\
log\left( \cfrac{1}{64} \right)=-\cfrac{tlog(2)}{29}\implies \cfrac{-29log\left( \frac{1}{64} \right)}{log(2)}=t\implies 174=t

since in 1910 t = 0, 174 years later from 1910, is 2084, so in 2084 they'll be 125 exactly, so the next year, 2085, will then be the first year they'd fall under that.
