If person earned a score higher than 35 persons in his class of 50 students, what is the percentile score?

divide and the subtract

answer:

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

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14
