The rule for a rotation by 180° about the origin is (x,y) -->(−x,−y)

So A(-3, 2) to A'(3, -2)

Answer:

A'(3, -2)

Step-by-step explanation:

<u>Step 1: Define</u>

<u /> $\displaystyle \frac{6}{19} = \frac{x - 12}{2x - 2}$ <u />

<u />

<u>Step 2: Solve for </u><em><u>x</u></em>

Cross-multiply: $\displaystyle 6(2x - 2) = 19(x - 12)$
Distribute: $\displaystyle 12x - 12 = 19x - 228$
Isolate <em>x</em> terms: $\displaystyle -12 = 7x - 228$
Isolate <em>x</em> term: $\displaystyle 216 = 7x$
Isolate <em>x</em>: $\displaystyle \frac{216}{7} = x$
Rewrite: $\displaystyle x = \frac{216}{7}$

Solve for w.<br><br> 5w + 9z = 2z + 3w<br><br> w = z<br> w = z<br> w = –2z<br> w = –7z

Semenov [28]

5w + 9z = 2z + 3w

Move terms with w to the left - subtract 3w from both sides

2w + 9z = 2z

Subtract 9z from both sides

2w = -7z

Divide both sides by 2

w = $\frac{-7}{2}z$
