g(x)=7x
Now
[tex]\\ \sf\longmapsto g(x)>28[/tex]
[tex]\\ \sf\longmapsto 7x>28[/tex]
[tex]\\ \sf\longmapsto x>\dfrac{28}{7}[/tex]
[tex]\\ \sf\longmapsto x>4[/tex]
Step-by-step explanation:
we have
g(x)=7x
We have to find the value of x when g(x) > 28.
[tex]\longrightarrow g(x)>28\\\\\longrightarrow 7x> 28\\\\\longrightarrow x> \dfrac{28}{7}\\\\\dashrightarrow x> 4 [/tex]
