Answer:

$\boxed {x = 2}$

Step-by-step explanation:

Solve for the value of $x$ :

$-\frac{2}{3}x + 3 = \frac{2}{3}x + \frac{1}{3}$

-Take $\frac{2}{3}x$ and subtract it from $-\frac{2}{3}x$ :

$-\frac{2}{3}x + 3 -\frac{2}{3}x = \frac{2}{3}x - \frac{2}{3}x + \frac{1}{3}$

$-\frac{4}{3}x + 3 = \frac{1}{3}$

-Subtract both sides and convert $3$ to a fraction:

$-\frac{4}{3}x + 3 - 3 = \frac{1}{3} - 3$

$-\frac{4}{3}x = \frac{1}{3} - \frac{9}{3}$

Since both $\frac{1}{3}$ and $\frac{9}{3}$ have the same denominator, then you would subtract the numerator:

$-\frac{4}{3}x = \frac{1 - 9}{3}$

$-\frac{4}{3}x = \frac{8}{3}$

-Multiply both sides by $-\frac{3}{4}$ , which is the reciprocal of $-\frac{4}{3}$ :

$x = \frac{8}{3} (-\frac{3}{4})$

$x = \frac{-8(-3)}{3 \times 4}$

$x = \frac{24}{12}$

-Divide $24$ by $12$ :

$x = \frac{24}{12}$

$\boxed {x = 2}$

So, therefore, the value of $x$ is $2$ .

Triangle ABC has vertices A, B and C at points (-3,4), (-3,0) and (-1,3), respectively.

1. First transformation is rotation by 90° anti-clockwise about the origin. This transformation has a rule:

(x,y)→(-y,x).

Then

A(-3,4)→A''(-4,-3);
B(-3,0)→B''(0,-3);
C(-1,3)→C''(-3,-1).

2. Second transformation is translation 2 units to the right with a rule

(x,y)→(x+2,y).

Then,

A''(-4,-3)→A'(-2,-3);
B''(0,-3)→B'(2,-3);
C''(-3,-1)→C'(-1,-1).

Answer: First transformation is rotation by 90° anti-clockwise about the origin, second transformation is translation 2 units to the right.
