Find the coordinates of the vertices of the triangle if it’s rotated 270° counterclockwise.
Scilla [17]

If these coordinates are rotated 270° counterclockwise, the resulting coordinates will be;

<em>X' = (3, -1)</em>

<em>Y' = (2, -2)</em>

<em>Z' = (-1, -3)</em>

<h3>Rotation of coordinates</h3>

If the coordinates (x, y) is rotated 270° counterclockwise, the resulting coordinate point will be;

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

From the given triangles, the coordinate points are expressed as

<em>X = (1, 3)</em>

<em>Y = (2, 2)</em>

<em>Z = (3, -1)</em>

If these coordinates are rotated 270° counterclockwise, the resulting coordinates will be;

<em>X' = (3, -1)</em>

<em>Y' = (2, -2)</em>

<em>Z' = (-1, -3)</em>

Which statement about the equation 3x ^ 2 + 9x - 12 = 0 is true ? 1 . The product of the roots is -12 . 2 The product of the roo
svetlana [45]

Answer:

Option : The product of the roots is - 4

Step-by-step explanation:

3x^2 + 9x - 12 = 0\\\\3x^2 + 12x - 3x - 12 = 0\\\\3x(x+4) -3(x+4) = 0\\\\(3x - 3) (x+ 4) = 0\\\\

Therefore the roots are -4 and 1

The product of the roots are -4 x 1 = -4
