Answer:

1. (-3,2) and (-1,2)

Step-by-step explanation:

Reflection over x axis results in change y-coordinates to opposite sign and x-coordinates remain as is

<u>So the coordinates become:</u>

A(-3, -2) → A'(-3, 2)
B(-1, -2) → B'(-1, 2)

Correct option is the first one

Penelope jogs three laps around the playground to keep in shape. The playground is rectangular with width of 163 m and a length

antoniya [11.8K]

The total amount of meters in one lap is 966 m

<h3>Further explanation</h3>

To solve the above questions, we need to recall some of the formulas as follows:

Area of Rectangle = Length × Width

Perimeter of Rectangle = 2 × ( Length + Width )

<em>Let us now tackle the problem !</em>

$\texttt{ }$

<u>Given:</u>

Length of Rectangle = L = 320 m

Width of Rectangle = W = 163 m

<u>Unknown:</u>

Perimeter of Rectangle = P = ?

<u>Solution:</u>

This problem is about Perimeter of Rectangle.

<em>The total amount of meters in one lap is equal to the perimeter of playground.</em>

<em>Let's find the perimeter of Rectangle.</em>

$\texttt{Perimeter of Rectangle} = 2 (\texttt{Length} + \texttt{Width})$

$P = 2 ( L + W )$

$P = 2 ( 320 + 163 )$

$P = 2 ( 483 )$

$P = \boxed {966 ~ \texttt{m}}$

$\texttt{ }$

<h2>Conclusion:</h2>

The total amount of meters in one lap is 966 meters

Answer using elimination will mark brainist<br> -4x+3y=-5<br> 4x-5y=3<br><br> 2x+3y=36<br> 10x-6y=12

Oksanka [162]

Answer:

Step-by-step explanation:

For Case -1

$\Rightarrow -4x+3y=-5\quad \ldots(i)$

$\Rightarrow 4x-5y=3$

$\Rightarrow 4x=5y+3$

Put the value of $4x$ in equation $(i)$ we get

$\Rightarrow -(5y+3)+3y=-5$

$\Rightarrow -5y+3y-3=-5$

$\Rightarrow 2=2y$

$\Rightarrow y=1$

and thus $4x=5(1)+3$

$x=\frac{8}{4}=2$

Case-2

$10x-6y=12\quad \ldots(i)$

$2x+3y=12\quad \ldots(ii)$

Now multiply $(ii) by 5 and subtract it from (i)$

$10x-6y=12$

$10x+15y=+180$

$\cdots \cdots \cdots$

$-21y=-168$

$y=8$

and $=6$
