Make use of structure. For rectangle ABCD, two vertices are A(-2, 3) and B(4, 6). Find the slopes of BC, CD, and DA. Explain you

MrRissso [65]

We are given a rectangle ABCD

A(-2, 3)

B(4, 6)

We are asked to find the slopes of sides BC, CD, and DA.

Let me first draw a rectangle to better understand the problem

Recall that the slope is given by

$m=\frac{y_2−y_1}{ x_2−x_1}$ $\text{where}(x_1,y_1)=(-2,3)\text{and}(x_2,y_2)=(4,6)$

So the slope of side AB is

$m_{AB}=\frac{6-3}{4-(-2)}=\frac{3}{4+2}=\frac{3}{6}=\frac{1}{2}=0.5$

The sides BC and DA are perpenducluar to the side AB.

So their slopes will be

$m_{BC}=m_{DA}=\frac{1}{-m_{AB}}$

Substituting the value of slope of AB

$m_{BC}=m_{DA}=\frac{1}{-0.5}=-2$

The side CD is parallel to the side AB.

Parallel sides have equal slopes so

$m_{CD}=m_{AB}=\frac{1}{2}$

Therefore, the slopes of the rectangle ABCD are

$\begin{gathered} m_{AB}=m_{CD}=\frac{1}{2} \\ m_{BC}=m_{DA}=-2 \end{gathered}$

Identify each value of x that makes 11 + 2x < 13

MatroZZZ [7]

Answer:

x < 1

Step-by-step explanation:

This is the answer because:

1) 11 + 2 = 13 and 13 is not less than 13, it is equal to 13. Therefore, x has to equal anything less than 1 because then only inequality statement will be true.

Therefore, the answer is x < 1.

Hope this helps! :D

You are running a concession stand at a basketball game. You are selling hot dogs and sodas. Each hot dog costs $1.50 and each s

nikklg [1K]

Answer:

35 hotdogs and 52 sodas sold.

Step-by-step explanation:

x = the number of hotdogs sold, x>0

y = the number of sodas sold, y>0

At the end of the night you made a total of $78.50:

1.50x + 0.50y = 78.50

You sold a total of 87 hotdogs and sodas combined:

x + y = 87

We have the following system of equations:

1.50x + 0.50y = 78.50

x + y = 87

A bank account balance, b, for an account starting with s dollars, earning an annual interest rate, r, and left untouched for n

Oduvanchick [21]

Well, assuming is "simple interest" rate

$\bf \qquad \textit{Simple Interest Earned Amount}\\\\
A=P(1+rt)\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to& \$200\\
r=rate\to 4\%\to \frac{4}{100}\to &0.04\\
t=years\to &10
\end{cases}$
