Which value or values for the variable c from the set below will make 5.6 + 0.4c ≀ to 6c true? {0, 0.875, 1, 2.5

Question
Answer:
We are given this inequality here,[tex]5.6+0.4c\leq6c[/tex]Now we have to check for the given values of c, that is true for this inequality.1. when c=0LHS: 5.6 + 0.4c= 5.6+0.4(0)=5.6RHS: 6c =6(0)=05.6≀0Not true for c=0.2. when c=0.875LHS: 5.6 + 0.4c= 5.6+0.4(0.875)=5.95RHS: 6(0.875) =5.255.95≀5.25Not true for c=0.8753. when c=1LHS: 5.6 + 0.4c= 5.6+0.4(1)=6RHS: 6c =6(1)=66≀6True for c=1.4. when c=2.5LHS: 5.6 + 0.4c= 5.6+0.4(2.5)=6.6RHS: 6c =6(2.5)=156.6≀15 True for c=2.5.Answer: The given inequality is true for c=1 and c=2.5
