Lesson 7.6 Properties of Systems of Linear Equations Exercises
... 4. a) Write each equation in slope-intercept form to identify the slope. i) –x + y = 5 y=x+5 The coefficient of x is 1, so the slope is 1. ii) –x – y = 10 –y = x + 10 y = –x – 10 The coefficient of x is –1, so the slope is –1. iii) –2x + 2y = 10 2y = 2x + 10 y=x+5 The coefficient of x is 1, so the s ...

The Hasse–Minkowski Theorem Lee Dicker University of Minnesota, REU Summer 2001
... km ≥ 1 + m for k ≥ 2, we have f (αm−1 + ξ0 pm ) ≡ 0 (mod pm+1 ). In addition m ≥ 1, so αm−1 + ξ0 pm ≡ γ (mod p) and we see that we may take αm = αm−1 + ξ0 pm . We now check that the sequence (3) converges p-adically. By construction, vp (αm − αm−1 ) ≥ m (here vp (ξ), ξ ∈ Qp is the p-adic value of ξ) ...
