the image of abc is a'b'c. what transformations would result in this image?

abc is reflected over the line x = 1, then is rotated -90° around the origin.
abc is reflected over the line y = x - 1, then t: (x, y) → (x - 1, y - 1).
abc is rotated 90° around the origin, then is reflected over the y-axis.
abc is rotated -90° around the origin, then is reflected over the line y = -1.

Ageologist had two rocks on a scale that weighed 4.6 kilograms together.rock a was 0.5 of the total weight.how much did rock a weigh?

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.
