Answer :
The given equation is:
[tex]y=4x+30[/tex]When x = 3;
[tex]\begin{gathered} y=4(3)+30 \\ y=12+30 \\ y=42 \end{gathered}[/tex]when x = 4;
[tex]\begin{gathered} y=4(4)+30 \\ y=16+30 \\ y=46 \end{gathered}[/tex]when x = 5;
[tex]\begin{gathered} y=4(5)+30 \\ y=20+30 \\ y=50 \end{gathered}[/tex]
