What is the answer for x?
5=-2.5x+8

Given: lines a and b are parallel and line c is a transversal. prove: 2 is supplementary to 8 what is the missing reason in the proof? statement reason 1. a || b, is a transv 1. given 2. ∠6 ≅ ∠2 2. ? 3. m∠6 = m∠2 3. def. of congruent 4. ∠6 is supp. to ∠8 4. def. of linear pair 5. ∠2 is supp. to ∠8 5. congruent supplements theorem corresponding angles theorem alternate interior angles theorem vertical angles theorem alternate exterior angles theorem

Use the quadratic function to predict f(x) if x equals 8. f(x) = 25x2 − 28x + 585

Solve the equation: x - 9 = -6 + 5 a. 21 b. 7 c. 14 d. 2
