Make a conjecture based on the given information. Draw a figure to illustrate your conjecture. Lines \(\ell\) and \(m\) are perpendicular.
Determine whether each conjecture is true or false. Give a counterexample for any false conjecture. Given: \(m+y \geq 10, y \geq 4\) Conjecture: \(m \leq 6\)
use the following information. Hydrocarbons are molecules composed of only carbon (C) and hydrogen (H) atoms. The simplest hydrocarbons are called alkanes. The first three alkanes are shown below. (TABLE NOT COPY) The expression \(n^{2}-n+41\) has a prime value for \(n=1\) \(n=2,\) and \(n=3 .\) Based on this pattern, you might conjecture that this expression always generates a prime number for any positive integral value of \(n .\) Try different values of \(n\) to test the conjecture. Answer true if you think the conjecture is always true. Answer false and give a counterexample if you think the conjecture is false. Justify your reasoning.
Determine whether each conjecture is true or false. Give a counterexample for any false conjecture. Given: \(n\) is a real number. Conjecture: \(n^{2}\) is a nonnegative number.
Determine whether each statement is always, sometimes, or never true. Explain. Two angles that are nonadjacent are vertical.
