Can someone please help

Explain how you do each step what term makes it inconsistent y=2x - 4 ?

Which of the following transformations will always produce a congruent figure?

One of the complementary angles is 4 degrees mor than the other. find the angles (recall that complementary angles are angles whose sum is 90 degrees.) which of the following can not be used to solve the problem if x represents one of the angles? a. 2x-4=90 b. 2x+4=90 c. x+4=90
