What is the slope of the line that passes through the points (9, 2) and
vlada-n [284]

Answer:

Slope (m) = infinity

Step-by-step explanation:

Given points:

⇒ (9, 2) and (9, 27)

In order to find the <em>slope</em> of these points, we must use the <em>slope</em> formula.

So the formula is ⇒ y₂ - y₁ / x₂ - x₁

<em>Plug</em> in the<em> given </em>points:

⇒ 27 - 2 / 9 - 9

Solve both the top and bottom (<em>numerator and denominator</em>):

⇒ 25 / 0

Divide:

⇒<em> Undefined. </em>

(<em>Anything</em><em> </em>divided by <em>zero</em> is undefined).

From the figure, the vertices of the given triangle are
(-3,4), (1,3) and (5,5).

The given transformation is (x,y) -> (x+3, y-2).
Therefore the coordinates of the transformed triangle are
(-3+3,4-2), (1+3,3-2), (5+3,5-2) = (0,2), (4,1), (8,3)

The transformed triangle is shown in red color.

Joey invest $900 at 4% simple interest for 2 years but he wants to know how much money he will have after only 18 months. Determ
malfutka [58]
Well, bearing in mind that, a year has 12 months, so 18 months is really just 18/12 of a year, or 3/2 a year, then

\bf \qquad \textit{Simple Interest Earned Amount}\\\\&#10;A=P(1+rt)\qquad &#10;\begin{cases}&#10;A=\textit{accumulated amount}\\&#10;P=\textit{original amount deposited}\to& \$900\\&#10;r=rate\to 4\%\to \frac{4}{100}\to &0.04\\&#10;t=years\to \frac{18}{12}\to &\frac{3}{2}&#10;\end{cases}&#10;\\\\\\&#10;A=900\left( 1+0.04\cdot \frac{3}{2} \right)

the population of masterton was 23 000 in 2012. Assume that Masterton population increases at a rate of 2% per year. Write an eq
Oksanka [162]
So, let's first focus on the first year:

the population then would be: 23000* (100+2)%

100% is the old population the 2% is the incease, so in total it's 102%, or 1.02 - the same number written differently.

So it will be 23000*1.02

After two years it will be 23000*1.02*1.02, and so on

so after x years it will be:

y=23000*1.02^{z}
