consider the inequality
[tex]3x-5<\text{ 8}[/tex]
this is equivalent to:
[tex]3x<\text{ 8 + 5}[/tex]
this is equivalent to
[tex]3x<\text{ 8 + 5 = 13}[/tex]
this is equivalent to say:
[tex]3x<\text{ 13}[/tex]
solve for x:
[tex]x<\text{ }\frac{13}{3}=4.3[/tex]
so, the correct answer for the second problem is (C) 4.5 , because 4.5 > 4.3 so 4.5 is not in the interval ( -infinity,4.3)
For problem 1, note that we have the following interval
[tex](-\infty,4.3)[/tex]
on the Real line that is:
