Answer:

[tex]z\geq 5[/tex]

The number is at least 5

Step-by-step explanation:

The inequality that represent this problem is

[tex]3z+4 \leq 4z-1[/tex]

because, the phrase "no more than" is the same that "less than or equal to"

Solve for z

[tex]4+1 \leq 4z-3z[/tex]

[tex]5 \leq z[/tex]

Rewrite

[tex]z\geq 5[/tex]

therefore

The number is at least 5.
