Answer:

$-\frac{5}{7}$

Step-by-step explanation:

Slope formula:

↓

$\frac{Y_2-Y_1}{X_2-X_1}$

$\frac{(-3)-2}{3-(-4)}=\frac{-5}{7}=-\frac{5}{7}$

<em>-5/7 is the correct answer. </em>

Finding the slope using the two points:

The formula for slope is

$\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

In this case...

$y_{2} =-3\\y_{1} =2\\x_{2} =3\\x_{1} =-4$

^^^Plug these numbers into the formula for slope...

$\frac{-3-2}{3 - (-4)}$

$\frac{-5}{7}$

^^^This is your slope

Hope this helped!

<h3>Finance charge</h3>

Using this formula

Finance charge=(Monthly payment× Number of payment)-(Purchase price-Down payment)

Let plug in the formula

Finance charge=($22.50×12)-($225.75-$25)

Finance charge=$270-$200.75

Finance charge=$69.25

Therefore the Finance charge is: d.) $69.25.

What is the area of the figure in the picture above?

jek_recluse [69]

The square area is 6*6=36
For the two triangles, the area is base*height/2 = 6*3 = 18.
So the total area is 18+36+18=72

NEED EXPLANATION PLEASE

Answer:

170 km on the ground
15 km over water

Step-by-step explanation:

Let t represent the amount of time spent over level ground. Then 5.75-t is the time spent over water. The total distance covered is ...

distance = speed · time

40(t) + 10(5.75 -t) = 185

30t + 57.5 = 185

30t = 127.5

t = 4.25

40t = 170

185 -170 = 15

The hovercraft covered 170 km on the ground and 15 km on the water.

Can someone please help with transformations of parent functions

Anna71 [15]

$\bf \qquad \qquad \qquad \qquad \textit{function transformations}
\\ \quad \\\\
% left side templates
\begin{array}{llll}
f(x)=&{{ A}}({{ B}}x+{{ C}})+{{ D}}
\\ \quad \\

\\ \quad \\
f(x)=&{{ A}}\sqrt{{{ B}}x+{{ C}}}+{{ D}}
\\ \quad \\
f(x)=&{{ A}}(\mathbb{R})^{{{ B}}x+{{ C}}}+{{ D}}
\\ \quad \\
f(x)=&{{ A}} sin\left({{ B }}x+{{ C}} \right)+{{ D}}
\end{array}\\\\
--------------------$

$\bf \bullet \textit{ stretches or shrinks horizontally by } {{ A}}\cdot {{ B}}\\\\
\bullet \textit{ flips it upside-down if }{{ A}}\textit{ is negative}\\
\left. \qquad \right. \textit{reflection over the x-axis}
\\\\
\bullet \textit{ flips it sideways if }{{ B}}\textit{ is negative}\\
\left. \qquad \right. \textit{reflection over the y-axis}$

$\bf \bullet \textit{ horizontal shift by }\frac{{{ C}}}{{{ B}}}\\
\left. \qquad \right. if\ \frac{{{ C}}}{{{ B}}}\textit{ is negative, to the right}\\\\
\left. \qquad \right. if\ \frac{{{ C}}}{{{ B}}}\textit{ is positive, to the left}\\\\

\left. \qquad \right. if\ {{ D}}\textit{ is negative, downwards}\\\\
\left. \qquad \right. if\ {{ D}}\textit{ is positive, upwards}\\\\
\bullet \textit{ period of }\frac{2\pi }{{{ B}}}$

that said, compressing vertical |x| by a factor of 4, means A = 4, thus is 4|x|.
