What are the coordinates of A" if it is reflected over the y-axis?

(3,1)

Step-by-step explanation:

When reflecting over the y-axis if the point was on quadrant 1, then the coordinated must be changed like so (x,y) -> (-x,y), so therefore in the scenario, all we have to do is reverse this process. So in this case, Point A is (-3,1) so all we have to do is change the -3 to a positive 3 to the the coordinates of A'' which is (3,1).

17

step-by-step explanation:

51/3=17

thus 17 is your answer.

answer:

c) the x-coordinate of the center of the circle increases by 3
