Which of the following equations have exactly one solution?
1. 52x+52=52x−78
2. 58x+52=−78x−78
3. −78x+52=−52x−78
4. 58x+52=78x−78

Solve by any method (graphing, substitution or linear combination)y = x - 82x + 3y = 1a) (2, -6)b) (5, -3)c) (4, -4)d) (0, -8)i figured it out. the answer is (5, -3)

Given: hf || jk; hg ? jg prove: fhg ? kjg to prove that the triangles are congruent by asa, which statement and reason could be used as part of the proof? fgh ? kgj because vertical angles are congruent. jkg ? hfg because vertical angles are congruent. fhg ? jkg because right angles are congruent. hfg ? kjg because alternate interior angles are congruent.

Idon’t understand! use slope intercept form to solve: through: (2,5) slope= undefined
