Murphy and naryam do thier math homework together. when they find 9 - (-8), they get different answers. murphy claims the difference is 17. naryam claims the difference is -1. what error likely led to the incorrect answer?

step-by-step explanation:

hello there!

i believe the answer is

(cot2+1)/sec2=cot2

    csc2/sec2=cot2

  (1/sin2)/(1/cos2)=cot2

  (1/sin2)(cos2/1)=cot2

  cos2/sin2=cot2

  (1/tan2)=cot2

  (cot2)=(cot2)

hope this !

parallel lines have the same slope. so if the green line has a slope of -4, the slope of the red line is also -4.
