00 points ! missy’s rotation maps point k(17, –12) to k’(12, 17). which describes the rotation? 270° counterclockwise rotation 90° counterclockwise rotation 90° clockwise rotation 180° rotation

90° counterclockwise rotation

Plot the situation

90° counterclockwise rotation

Step-by-step explanation:

A 90° counterclockwise rotation maps every point (x, y) to (-y, x).

K(17, -12) is mapped to K'(12, 17).  The x- and y-coordinates are switched and the y-coordinate is negated (before being switched).  This means

(x,y)→(-y,x).

This is a 90° counterclockwise rotation.

step-by-step explanation:

1/4 = .25 / 25%

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
