HELP PLSSS ! which graphs do not show a constant rate of change? check all that apply

30 determine the coefficient on x 12 y 24 x12y24 in ( x 3 + 2 x y 2 + y + 3 ) 18 . (x3+2xy2+y+3)18. (be careful, as x x and y y now appear in multiple terms! )

Determine whether the angles in each given pair are coterminal. 744°, -336°

Segment xz is bisected by point y. if xy = 12x, and the measure of xz = 18x – 6, solve for x
