Answer:

x=8

Step-by-step explanation:

3x-15=17-x  move variable to the left and change its sign

3x+x-15=17  collect like terms

4x=17 + 15 (3x=x=4x)

4x= 32  divide both sides by 4

x=8   (dividing 4x by 4 cancels the 4,s out and leaves x)

The population of a town in 2000 was 430. The population is increasing at a rate of 0.9% every year. What will be the projected
Naddik [55]
If in 2000 there were 430 folksk, 2010 is 10 years later, thus t = 10

\bf \qquad \textit{Amount for Exponential Growth}\\\\
A=I(1 + r)^t\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
I=\textit{initial amount}\to &430\\
r=rate\to 0.9\%\to \frac{0.9}{100}\to &0.009\\
t=\textit{elapsed time}\to &10\\
\end{cases}
\\\\\\
A=430(1+0.009)^{10}\implies A=430(1.009)^{10}

What is the vertical and horizontal aysmptote of g(x)=10/x
garik1379 [7]
The vertical asymptote is where the function does not exist (denominator ≠ 0) <span>So set the denominator equal to 0 and solve for x.</span>
vertical asmyptote is x = 0

the horizontal asymptote is the behavoir of the function as x goes to +/- infinity. As x get's larger in value the y-value get's closer and closer to zero.
example: {x = 9, 99, 999, 9999} then {y =1/9, 1/99, 1/999, 1/9999...}
horizontal asmptote is y = 0

Two gyms open their memberships to the public. Compare the gyms by calculating and interpreting the average rates of change from
Alenkasestr [34]

Answer:

Gym A gets 52 people per week and Gym B gets 62 people per week. So, Gym B is growing faster.

Step-by-step explanation:

To find the average membership in Gym A is simple. To get 72 to 124, we need to subtract them getting 52, this is the same for the other weeks. So, Gym A gets 52 members per week. Gym B is a bit more complex, each week has to be constant so subtract 204 by 80 and you get 124. Divide 124 by 2 because the difference between Week 1 to 3 is 2. Then we get 62 some Gym B gets 62 average members per week. Hope this helps. Gym A gets 52 people per week and Gym B gets 62 people per week. So, Gym B is growing faster.
