Select one of the factors of x2y3 − 11x2y + 6y2 − 66

Varies inversely with x. if y=8.5 when x=-1 find x when y=-1

The construction of copying qpr is started below. the next step is to set the width of the compass to the length of ab. how does this step ensure that a new angle will be congruent to the original angle? by using compass take the measures of angle and draw the same arc according to it.

Which angle is the smallest? also give me an explanation so i can complete it to other questions as well, : )
