Which systems have infinite solutions? check all that apply.
y = 0.5x + 2.75 and 2y = x + 2.75
y = 0.5x + 2.75 and y – 0.5x = 2.75
y = 0.5x + 2.75 and 0.5x + y = 2.75
y = 0.5x + 2.75 and y = 0.5(x + 5.5)
y = 0.5x + 2.75 and y = –2(–0.25x )+ 2.75

Which is a logical conclusion based on the given information? a. figure abcd is a rhombus by the definition of a rhombus. b. segment ac is congruent to segment dc by cpctc. c. angle acb is congruent to angle adc by the angle-side-angle theorem. d. triangle acd is congruent to triangle cab by the hypotenuse-leg theorem.
