What type(s) of symmetry does this figure have?

kirza4 [7]

It's for sure reflection symmetry, I think it's also point reflection (the point must be in the very middle of the figure). I hope it will help you somehow :)

Whats the distance between (-8,-7) (8,-4)

balandron [24]

To find the distance between points, use the distance formula.

Distance formula: $\sqrt{ (x_{2} - x_{1})^{2} + ( y_{2} - y_{1})^{2} }$

Plug in your values for $x_{2}, x_{1}, y_{2}, y_{1}$ using (-8, -7) and (8, -4) and solve.

$\sqrt{(8 - (-8))^{2}+(-4 - (-7))^{2}}$
$\sqrt{(8+8)^{2}+(-4+7)^{2}}$
$\sqrt{(16)^{2}+(3)^{2}}$
$\sqrt{256+9}$
$\sqrt{265}$ ≈ $16.28$

Answer:
Approximately 16.28 units.

Y=-3x - 4 y= 2x + 1

Naily [24]

$\left \{ {{y=-3x-4} \atop {y=2x+1}} \right. \\\\ substitution\ method\\\\
-3x-4=2x+1\ \ \ | subtract\ 2x\\\\
-5x-4=1\ \ \ | add\ 4\\\\
-5x=5\ \ \ | divide\ by\ -5\\\\
x=-1\\\\
y=2x+1=2*(-1)+1=-2+1=-1\\\\
Solution:\\ \left \{ {{y=-1} \atop {x=-1}} \right.$
