Answer:

(-2, -3)

Step-by-step explanation:

90° clockwise rotation:

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

Let's apply this to our coordinates:

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

(3, -2) -----> (-2, -3)

Simply make the old y-coordinate the new x-coordinate, and make the old x-coordinate negative and make the new y-coordinate.

Therefore, the coordinate of the new point is (-2, -3).

Solve using Quadratic Formula <br>x^2 + 3x - 3 = 0

katrin [286]

Answer:

a= 1 , b= 3 , c= –3

$x = \frac{ - b \frac{ + }{} \sqrt{ {b}^{2} - 4ac} }{2a} \\ x = \frac{ - 3 \frac{ + }{} {} \sqrt{ {3}^{2} - 4(1)( - 3)} }{2(1)} \\ = \frac{ - 3 \frac{ + }{} \sqrt{9 + 12} }{2} = \frac{ - 3 \frac{ + }{} \sqrt{21} }{2} \\ \\ x = \frac{ - 3 \frac{ + }{} \sqrt{21} }{2} \\ \\ x = 0.79 \\ x = - 3.79$
