The coordinates of the vertices of quadrilateral cdef are c(6, 6), d(6, 8), e(8, 10), and f(10, 8). the figure is rotated 90° about the origin. what are the vertices of the resulting image, figure c’d’e’f’? drag numbers to complete the coordinates. numbers may be used once, more than once, or not at all.

Answer/Step-by-step explanation:

If the figure is rotated clockwise:

C'(6, -6); D'(8, -6); E'(10,-8); F'(8, -10)

If the figure is rotated counterclockwise:

C'(-6, 6); D'(-8, 6); E'(-10, 8); F'(-8, 10)

A clockwise rotation 90 degrees about the origin transforms a point (x, y) to (y, -x).

A counterclockwise rotation 90 degrees about the origin transforms a point (x, y) to (-y, x).

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
