14 What are the solutions to the equation 3(x − 4)² = 27?

Marat540 [252]

Answer:

(1) 1 and 7

Step-by-step explanation:

Hello!

We can solve by isolating the variable.

<h3>Solve</h3>

3(x - 4)² = 27
(x - 4)² = 9
√(x - 4)² = √9
(x - 4) = ± 3
x = 4 ± 3

There are two solutions, 1 and 7.

The answer is option 1: x = 7, x = 1.

Quadrilateral PQRS is transformed by translating it 6 units to the right and then rotating it 90° clockwise

Elina [12.6K]

Answer:

(y, -x -6)

Step-by-step explanation:

<em>The coordinates of PQRS is not given, however we'll assume the coordinates of PQRS to be (x,y)</em>

<em />

The first transformation: 6 units right

$(x,y) -> (x + b, y)$

Where b = 6

So, the new coordinates will be

$(x + 6, y)$

The second transformation: 90° clockwise

$(x,y) -> (y,-x)$

So, the new coordinates will be

$(x + 6, y)-> (y, -x -6)$

<em>Hence, the new coordinates of PQRS is (y, -x - 6)</em>
