Theorem axcontlem10 28907

Description: Lemma for axcont 28910. Given a handful of assumptions, derive the conclusion of the final theorem. (Contributed by Scott Fenton, 20-Jun-2013.)

**Hypotheses**
Ref	Expression
axcontlem10.1	⊢ 𝐷 = {𝑝 ∈ (𝔼‘𝑁) ∣ (𝑈 Btwn ⟨𝑍, 𝑝⟩ ∨ 𝑝 Btwn ⟨𝑍, 𝑈⟩)}
axcontlem10.2	⊢ 𝐹 = {⟨𝑥, 𝑡⟩ ∣ (𝑥 ∈ 𝐷 ∧ (𝑡 ∈ (0[,)+∞) ∧ ∀𝑖 ∈ (1...𝑁)(𝑥‘𝑖) = (((1 − 𝑡) · (𝑍‘𝑖)) + (𝑡 · (𝑈‘𝑖)))))}

**Assertion**
Ref	Expression
axcontlem10	⊢ (((𝑁 ∈ ℕ ∧ (𝐴 ⊆ (𝔼‘𝑁) ∧ 𝐵 ⊆ (𝔼‘𝑁) ∧ ∀𝑥 ∈ 𝐴 ∀𝑦 ∈ 𝐵 𝑥 Btwn ⟨𝑍, 𝑦⟩)) ∧ ((𝑍 ∈ (𝔼‘𝑁) ∧ 𝑈 ∈ 𝐴 ∧ 𝐵 ≠ ∅) ∧ 𝑍 ≠ 𝑈)) → ∃𝑏 ∈ (𝔼‘𝑁)∀𝑥 ∈ 𝐴 ∀𝑦 ∈ 𝐵 𝑏 Btwn ⟨𝑥, 𝑦⟩)

Distinct variable groups: 𝐴,𝑏,𝑝,𝑥 𝑁,𝑏,𝑝,𝑥,𝑦 𝑖,𝑍,𝑡 𝑍,𝑏,𝑝,𝑥,𝑦 𝐵,𝑏,𝑝,𝑥,𝑦 𝑖,𝐹,𝑡 𝐹,𝑏,𝑝,𝑥,𝑦 𝑈,𝑏,𝑦 𝑈,𝑖,𝑝,𝑡,𝑥 𝑖,𝑁,𝑡 𝐷,𝑝,𝑡,𝑥 Allowed substitution hints: 𝐴(𝑦,𝑡,𝑖) 𝐵(𝑡,𝑖) 𝐷(𝑦,𝑖,𝑏)

Proof of Theorem axcontlem10 Dummy variables 𝑘 𝑚 𝑛 𝑞 𝑟 are mutually distinct and distinct from all other variables.
